  1. Ok, no review yet because I am stuck. I can’t get past the keypads, I don’t know where to find the codes or a way to enter the other rooms.

    Any super smart PP readers out there?

    Whoops, sorry; all PP readers are super smart. DOH!

  2. bikerdude

    I have the same prob, I have used no clip to find out whats behind the doors, but thats not the point, where are the cluses to the key pads..?

  3. bikerdude

    I have found the author and droped him an email – I will come back with the result..

  4. Brian

    Really like it so far! Made it quite ways and see a set of numbers on a monitor but can’t get them to work

  5. bikerdude

    ah cool, what monitor..? (I havent had a reply from the author yet..

  6. Play It Now!

    Dude that was awesome. Last combat was really cool. I’ve never felt that surprised when I saw Combine soldiers before. Quite nasty. Puzzles were interesting and well balanced if you ask me. Visually very nice. Nothing spectecular but quite enough for this mod. Gameplay was very good. One of the best I’ve played lately.

    Action + Puzzles = Fun

    Codes are on board on the wall.

  7. Glad I’m not the only one stuck. Anyway, I just recieved this from Richard:
    Go to the section with the toilet-rooms, if you are looking to the men’s and womens toiletrooms, there is a large steel door to the right, it is opened only a little and if you duck you are not able to get in because the opening is not large enough , then press your “use”-key and after a strange cutscene you get into that room, you can also see the G-man, walking away from the toilets if you look back.

    I remember pressing a button and noticing that the door he mentioned had in fact raised a little but assumed something else had also happened.

    Gonna test it now.
    EDIT/ It works and you can continue.

  8. bikerdude

    well I found some codes, but if you do as suggested above you`ll find them just like I did…if you want to be lazy I can give them too you

  9. Neoka
    Play It Now!

    Found the codes, and last fight (I think) was fun, however I died, and didnt feel like starting all over -_- anyway, once you find the codes, your good, just remember them,

    Codes are 4 digits, and NEAR the monitor with all those numbers.

  10. Play It Now!

    Just finished the mod, I already emailed Phillip and see he has just posted what I found out, you have to use this “trick” several times in the mod (when you’re not able to get out of the lift and one or two times more)
    The final fight is really awesome, like CivanT allready mentioned , the codes you can find on a board on the wall somewhere, it’s not that hard to find.
    A very nice short mod ,allthough a little too dark, I prefer outside area’s , still nice to play.

  11. Brian
    Personal Favourite

    Had to up my rating after finishing!

  12. Robspace1

    Well, I’m stuck like all of you were. Now, I see the big door by the toilets and yes, I could not get under it but now will try the “use” key. So, far this thing is giving me a nice headacke with the sirens going off and no idea where to go next. I really like games that give some kind of an idea on where to go next. This place has so many doors with key pads that I am completely lost as to the next move. \
    The author should have made the map a litlle easier to navigate. Since everyone so far has had the same problem finding their way through it, I think the problem is with the way the map is made and not the intelligence level of the players. We all play these mods alot and if we get lost, you can pretty much count on this happening to just about everyone else that plays it.

  13. Robspace1
    Play It Now!

    Real good! To the author. sorry if I sounded a tad rough about the way the player has to find their way through at the beginning, but the rest of the mod more then makes up for the beginning which if left the way it is, will no doubt confuse alot of people.
    All the different doors made it confusing as to where to go next. I would rather have spent that time fighting the enemy and not fooling around trying to get a door to open, just to find that it’s not the right one anyway.(Shades of Winchesters Mystery House) doors to nowhere.

    The elevator ride was great! It was downright scary. The ugly noise of metal grainding and the feeling that this thing may drop to the bottom at any minute was fantastic. Well done. That part was really well made.

    Overall a good mod, could have been longer with more enemies but the ending was a nice suprise and the only thing that would have made it a little better would have been to allow Gordon to drive away into the sunlight after being cooped up fighting in some dank warehouse. Maybe have him drive away in a dune buggy across the face of Mars to some outpost. Or is that part 2? Hope so.

  14. MikeS

    I can’t say I’m enjoying this mod so far. I just seem to be running around, smashing boxes and pressing buttons/doors at random to proceed. There were a few zombies and combines to alleviate the boredom, but little else.

    Anyway, I’ve gone through several miles of airducts, and I’m now in a lab. There’s a door with a code, and a monitor displaying 4, 8, 15, 16, 23, 42 The keypad only permits 4 numbers to be entered though. *scratches head*

    1. imadestroyer

      Check out the bulletin board in that room. The 4, 8, 15… is a reference to the show Lost and it’s an easter egg in Episode 2. It has no relevance in this mod.

  15. Jeff
    Play It Later

    A very good mix of exploration and combat. I prefer more combat myself, but it’s still a very good mod. I only ever found two codes, and I never opened some doors. Maybe I missed a clue or they just aren’t important, but the packrat in me doesn’t like leaving areas unexplored, even if they’re unreachable.

  16. Mel

    OK found numbers, but how do you enter them into the key pad?

    1. Go upto the keypad and press your “use” key. The use your left and right strafe keys to select numbers and then you fire key to press a number.

  17. Hi guys

    I check my Email today and I found that map already is here xD Well I’m creating English version and fixing some bugs now πŸ™‚ I will release full English version soon ;]
    Anyway, I made a video “How to complete map”

    And thanks for comments I’m surprised to get so much great comments because… you know It’s my second map in Source Engine and It’s my FIRST released map for Source Engine :]

    I will do little changes with map and release it on my web or will contact Philip to add new map here πŸ˜‰

  18. I’ve just added a video walkthrough created by the author.

  19. 14 more screenshots added, definitel;y spoilers in those. I’ll finish playing another mod and then I’ll post my review of this.

  20. Play It Later

    Very good and much superior to MARS 002. A must play but I suggest a download to desktop and play when convenient.
    Hate flashing lights, too dark, crawling through far too many vents and it would have been much more fun with shotgun earlier on. Otherwise this would have been a PIN or even a personal favourite.
    Oops, the cat is chasing the mouse, better go.

  21. MikeS

    Perhaps if I’d played the final battle some of the above folks mentioned I’d give it a higher recommendation. But I gave up after I went up/down in the lift and found myself back where I started. As Jasper said, it’s too dark, the sirens become annoying and there is too much vent crawling. Then there are those keypads and consoles that are too numerous and their use rarely required….

    I feel ungrateful, considering the author spent hours creating this for us to play for nothing, but it just isn’t my cup of tea, hence the ‘maybe” non-recommendation.

  22. Gypsy Jim
    Play It Now!

    Well, as a later commenter I can’t help but agree with most of what has been posted already….

    Very dark, pretty frustrating, and a very limited layout that you have to revisit to get through to the finale…

    Still, even though it took me forever to work out the door code thing, (and I’m still not sure I didn’t miss something about that, seeing as how there were so many that didn’t seem to respond to the codes once I’d got there…) I did enjoy the Doom-esque air to it all, and the visual creepiness.

    Combat (played on Normal) came in winnable amounts, mostly, until the finale, which was almost an Arena map tagged onto the end……Great fun though.

    No story? Didn’t really matter.

    I too would have liked a clue or two about the doors, and didn’t remotely understand the early power switch thing, nor if or how it fitted in with making anything work….

    I don’t always want things spelling out, but prefer to have to go look for them, but this was a step beyond in most respects…

    On another subject, I know it was supposed to be set in a Mars base, but if we’re trying to be semi-realistic on architecture, then the unfeasibly complicated ventilation shaft area (with a headcrab around every other corner…) was more of a humorous poke at the original & quite a few other mods, rather than an asset for this one.

    Just my humble opinion.
    Still, I do give it a PIN and look forward to whatever else the author can conjure up……

  23. Robspace1

    There really is nothing new in this mod and you could take Mars out of the name and never miss it. It looks like any other warehouse on Earth. For those stuck in the control room, save alot of time and frustration and head over to where the glowing monitor is sitting on the ground. Look up to your right at the message board. You’ll see two numbers. You need these.
    Go back to the door and enter one set, of 4 numbers, the bottom set, I think, and then hit the use (e) key. To enter the numbers I used the A key and the D key as instucted.
    The Russian language only makes this harder to play and all the doors are a red herring.Most won’t open. Just head for the elevator and hit the E key again. I don’t like adding a spoiler, but this time it’s really needed as this is way too hard to figure, especially with the foreign language problem.

  24. I have added links to version 2, which includes English text.

    For some reason I didn’t like this map too much. It is not very nice looking, somewhat frustrating and not suitable to be played in “hard” mode (at least the end isn’t). Also the code-pads were a real bother (in R&D they were implemented much better).

    I liked the crouching under barley opened doors and out of the elevator, but I wish it could have been explained better – it took me a while to figure it out and I was stuck in the meantime.. All in all, not bad for a single map, but still a disappointment considering the many good opinions on this page!

  27. Play It Later

    Sweet small mod.
    It is made quite atmospheric and I like it how the atmosphere builds up until the end.
    The few new models were nicely made and the brushwork was solid, but nothing special.
    The fights were sometimes tactical, sometimes dumb.
    The last fight was a bit chaotic and I don’t like that arena type fights.
    What I didn’t like was that the code was hidden quite well, at first I stared at the numbers at the screen and riddled half an hour in what comparison they stand to each other and how to extract 4 digit numbers out of them.
    Also, what I hat at all of those Mars maps is, that you actually never see the Mars, you are ever walking inside a facility which could be also at the earth or somewhere else.

    Sorry lads, give this one a miss unless you like wandering around pressing buttons at random, trying to figure out why the author includes cut scenes rather than just letting ou crawl under the damn door – and of course there are those bledded keypads. Within 5 minutes I was bored beyond breaking point.

  29. Play It Later

    This was well done, though I had some issues, so it doesn’t get a PIN.

    The vent maze thing seemed a little pointless but it wasn’t a big deal, it just didn’t seem very realistic.

    It would be nice if there were some way to lead players away from the doors with keypads before you get the codes (maybe a little better lighting where you want them to go???). I went into the elevator room and got the .357 ammo. I went into the bathrooms and finally got the pipe/crowbar so triggered some enemies. Then I went into the control room for that area. I wasn’t sure what the button on the console did. I finally realized I needed a code for the keypads so wandered around breaking boxes to see if the code was written on a wall or floor or something. THEN I finally noticed the half-open door I was supposed to crawl under.

    The first elevator ride was especially well done, as said before.

    But when I got back upstairs, neither code worked on the two keypads sort of near the elevator. (I even reloaded a save and double-checked the numbers.) I don’t know if I was supposed to go in those rooms or not–because the codes didn’t work I just went on. (If those doors aren’t supposed to work, the keypads should be inactive as they were for later doors.)

    I liked the apparent shortage of ammo for the “good” weapons (.357 and SMG). Maybe better players than I didn’t notice. Like whomever said it above, I don’t understand why we couldn’t just crouch-walk under the doors instead of have the cut-scene, but that’s minor.

    Once I got going the right way (crawling under the door), this was a good mod.

  30. You know, I can’t for the life of me read what those numbers are on the bulletin board. On first glance they look like 6342 and 2459. The second number in each series is questionable so I’ve tried 1 through 9 in that spot with no success. My frustration level after trying so many possibilities has reached the point where I just want to ask… can someone tell me what the heck the right number is? Thanks.

    1. I got what you did for the second number. I didn’t find any place to use it (I may have written it down wrong). For the first, I got 6912.

      1. Yes. 6912 worked. I would have never guessed that by looking at it. But once I knew what it was and went back to look at it again I can see it now. Thanks.

    OK. I liked it. I was a little difficult to figure out at times. But that’s why we have our friends at Planet Phillip. Thanks guys.

    When I try to play this mod, it goes to the screen with the planet and the loading thing at the right bottom of the screen. After a few seconds later the screens black and returns back to the decktop giving me a massage saying: setupArrayProps_R: array prop “(null)” is at index zero. What is the problem.

    1. denizen50

      I get the same exact error

    because its a competition map I tend to review it a little easier. Its well made and after getting the codes it moves along quite well. as stated there are too many doors and keypads but a fun play nonetheless

    Didn’t actually play it. Tried fixing the steam problems by editing the gameinfo but that didn’t work. Would not start.
