Infiltration Mod – Half-Life 2

for Half-Life 2

Single Player First Person Shooter Maps and Mods for Half Life 1, 2 and 3
Author’s Notes

“Infiltration bases technically on the original game Half Life² from valve. The modification continues the story of the Shooter and offers an alternative action strand. You can integrate Infiltration in the HL²-storyline but it does not start at a certain point in the known story. Because the Mod is designed by hobby-designers, it will be a free download.

“Complete brain control in form of an implanted chip – a direful weapon for the Combine. Nearly all human beings in City 10 are subject already either to complete control or succumbed to the consequences of the radiation. The radiation is a product of the reactors, those secure the constant functionality of the chips. The last rebels are in a situation almost offering no prospects. Absolute control and the stop of the “normal” social life let a complete city collapse to itself. The craving for power and the control craze of the Combine are now exclusively directed against the rebellion, while the remaining population sinks in chaos. Selected civilians serve thus against their own will the regime of the occupying force. To fight against the own people may be bitter, but what if even your closest familiar ones are used in order to kill you? Save your friends from the control of the Combine but plan you. They will not hesitate an instant to extinguish you!

“The own story of the Mod leads the player through completely new provided locations. Own textures and environments provide a dark atmosphere. New weapons support the combat experience and the reunion of well-known characters let the Half-Life Feeling arise.”

  1. AI

    I tried the link and only got 6 to 7kbs DL, I’m not going to sit there for 9hrs! thanks anyway! I thought PP had DL’d already?

  2. He may of I dont know.Check the file cloud site.It took me 30 minutes to download from master server 3 about the same speed I get from file cloud and no waiting.

  3. AI

    Phillip, Did you DL this file yet? I can’t find it on File Cloud, and the only connection I can get is about 6 to 7kbs, ya I know boohoo!

  4. Phillip, Did you DL this file yet?

    It’s uploading to FIlecloud as I type. I’ll post the link and a new comment as soon as it’s done.

    I couldn’t find a patch so it has to be the full 1.31 version. :(

  5. Full version 1.31 has now been uploaded and a link to it posted in the main section.

  6. Play It Now!

    This version (1.3.1) is much better and resolved nearly all the bugs and graphics issues, except the following three (you may not have these):

    It still froze up once, after a cut scene, but playing from last save worked.

    At one point you are given the crossbow and following sequences call to use it since you are attacked by snipers. However the bow site reveals nothing but texture and bolts fail to kill shooters. For this sequence I had to use god mod and ignore shooters until past them.

    Also end credits will roll early without final pix if ending sequence kills you.

    Also. note for those that were playing the earlier version and had to give up, I was unable to use my game serves from that earlier version so had to play through first 8 levels on god mode to catch up.

    Still. I recommend this mod. I thought it was a lot of fun, challenging, a good balance between indoor/outdoor, and plenty of puzzles. Therefore I am changing my recomendation from “consider” to “recommend”

  7. tox_dev

    well, I’m just watching video, but not fun.

    story and effect is… a few(?) good,

    but, too many (maybe un_test) friendly bug,

    I hate it!

  8. Denizen

    Crash, crash, crash.

  9. Straven

    Looks Good D/Ling now.

    I’m playing the new one. The 1.31 version and I’m stuck at the same place as everyone was in the 1st one. In chapter 8 in the cutscene. The strider is walking but the scene never ends and I don’t get control back. This such a good mod, it’s completely unbeleivable that the people that made it would let it go with so many bugs and then even after they try to fix it with a new one it still has bugs. Why bother? The mod is real good but these stupid errors are euining the game for me. This the 3rd time it’s frozen up in this “new, improved version”. It also took about 10 hours to download and I have a fast connection. My dl speed is 12 mbps.

    Good and buggy-Actually the bugs were not all that bad. When you get to the bridge and you are fighting a chopper and then a Strider comes along and your in a cut scene. If the cut scene goes longer then 20 seconds, it’s stuck. Just start chapter 8 over and it should be ok. Also the end is strange but you’ll see. Kinda confusing. This is a good mod with a few bug problems. I really hope they finish the story and make sure it’s cleaned up before putting it out. Because of the bugs I don’t think it can get a top mark. It’s good though with a good story and lots of fighting.

  12. Dassin

    A good time waster. But, the plot and the game play. If Michael J. Caboose were to make a mod. This would be it.

  13. lacoon

    I’m currently playing the Infiltration mod. After you’re taken into the lab to meet Kleiner and Mossman and have your weapons taken away along with your HEV suit. My problem is that there doesn’t seem to be any way to get your suit back. There’s an HEV case in the lab, but it’s empty.

    I played several levels ahead and not found a suit. I even decompiled several maps to look for it to no avail. It’s hard to believe you’re supposed to play the rest of the mod without a flashlight and the ability to switch weapons.

    Any help would be appreciated.

    Lacoon, Pick up a weapon and hey presto! HEV.
    By the way, thanks. I had forgotten how good this mod is.
    It is no Offshore for sure but enjoyable and with quite a few elements of tough game play. Playing again now.

  15. Play It Now!

    Thanks Jasper. I have been picking up weapons to no effect, but now I know I can give myself a suit and continue playing without cheating.

    It’s been an interesting mod…
    The mapping is just decent however the fights are extremely well done with exactly the right amounts of health and ammo – these guys really know how to create a good fight – top marks from that point of view.
    The mapping bugs are plenty – more than once I’ve been able to “fall off the map” because I went to areas I wasn’t supposed to – but I’ve been able to reach those areas effortlessly. More testing would have helped… Also in some places the misaligned textures were clearly visible and mildly annoying.
    The only bug that I encountered (played version 1.31) was the strider never blowing up the bridge – quite annoying and forced me to replay the map from the beginning – fortunately this happens pretty close to the beginning of the map.
    Important thing to note about the energy bars blocking access into and out of the tunnel in level 12 after you destroy the chopper – they are no match for a determined player :) I was able to go through without disabling them and suffered only a minimal amount of damage. After I finished the mod I came here and read the comments, then went back to the map and found the part that I missed the first time – I guess this is a bug but who cares :)
    Spoiler: in the ending sequence after killing Sina I shot the gunship and died 😛 So after I loaded the save I tried to go back to a point where I could shoot the gunship without falling afterwards – the corridor entrance. As soon as I reached that the credits started rolling although I haven’t shot the gunship yet – weird bug I presume.

    At the end of it all it was enjoyable and that’s all that matters!

    ive given “HALF LIFE 2 Infiltration” a PIN since I actually enjoyed this mod…the only aspect of the game that concerned be was how dark it was at times,but apart from that this is a pretty impressive mod
    many may not like the comic book style storyboard,however its unique and never been done in any other mod… and you have time to read them and keep abreast with the story
    the ingame music was especially good with some really good compositions … and allthough its easy to simply add some hammer based sounds to your mod its allways nice to see fresh music and sounds
    alot of work went into this mod and when I first played it around 18 months ago (approx) it was still pretty buggy however it ran fine this time around and was a joy to play
    I would also like to comment on the main loading screen which was one of the best ive seen …
    in summary “”HALF LIFE 2 Infiltration” is up there with some of the best HL2 mods ( minerva,strider mountain and research and development ) and thoroughly deserves a “PLAY IT NOW “

    This mod is weird. I feel like three different people made it. One good mapper, one lazy mapper and one horrid mapper. My favourite part was the beginning, taking place in a rainy City 17. This part has excellent atmosphere and feels very oppressive. Then you get to a car and drive through the rest of C17 then escape. Everything changes here. The mapping becomes more sloppy, having multiple edges of the world leading into nothing but the void of nothingness right there for you to walk/run/jump/drive off. A lot of maps seem empty and baron. Maybe it’s because I just played Union, Leon’s Mappack and The Sprucecape Mappack, but I really do think they could use more parts. There are cutscenes in this mod as well, some just regular cutscenes and some comic-style. I love the comic book style ones and I love how there’s sounds in the background of them (footsteps for example) to make them seem more realistic within the world. There is one, however, glaring issue with these. On about ten different occasions after the comics I couldn’t move. Couldn’t look around either. Not even noclip helped me, I was just cemented to the ground, frozen like a nudist in the snow. I don’t fully understand the story, but I know it’s an alternate Episode One (even though it came out BEFORE Ep1 did), and I guess Alyx and Eli were captured and Freeman has to go save them. Speaking of the Vances, they butchered their spelling. “Eli Vans” sounds like a car dealer.

    At one point about halfway through the game you go to “Sio Prospekt”, a prison much like Nova. Then you go back to C17. This return to the city is easily the WORST part of the mod. Usually I like fighting Gunships and Striders but these battles had no strategy to them. It gives you one small safe zone from gunfire right across from the enemy and a box of infinite rockets right next to you. Then you go to an area that’s the worst offender of the “Edge of the World” syndrome. I counted at least four different ways to get to the void. Couldn’t they just have put a wall? What kind of city just ends like that? Must have been a nasty rebel attack! There are a few doors in this mod that don’t open, maker any sound when you try to open them or do the “locked” door handle animation. Pretty lazy if you ask me. But one thing that’s good about this mod is that there’s some places you don’t have to go but can, which, in my opinion, makes it more realistic and interesting. The custom skyboxes are really good too; unfortunately there’s a few invisible walls here and there that get a tad bit annoying. This mod is also pretty long, one of the longest ones I’ve reviewed so far, second only to DayHard and Minerva


    A later level is set in Ravenholm (an environment I love) but is unfortunately really short. It’s definitely the weakest Ravenholm level I’ve played so far. You can duck under one of the Combine forcefields in this level and it just leads to a wall. Pretty silly. Oh yeah, there’s also a random dancing Vort in the rebel base, have fun with that. There’s another brief return to the city and then you go into the “Combine Mothership”. Why not just make it a citadel? I don’t know, but this level is really fun! There’s some fun firefights with Overwatch Elites. Then apparently the “spy” from earlier betrayed everyone and killed Eli Vans. I honestly saw this plot twist coming. She’s basically a throwaway character and never does anything for the plot. You have to defeat her after she does some cheesy monologuing. She takes one or two pulse rifle bullets to the face and you’re done. Lamest final boss ever. The ending also seems rushed, you shoot a dead gunship and it destroys something, then “Alyx Vans” is free. The end.


    At least play the first level. If you can’t stand the next ten or twenty minutes, you’ll probably hate the rest of the mod.

    This was a very misleading modification it does have many good qualities, but I found the bad qualities really over-shadow this modification, and left me cringing.

    Most of the problems in this modification could have easily been fixed or edited out. This is one of those modifications that looks “Good Far-Away But Once You Get Up Close You Want To Back Away”.

    Viewing some of the minor problems that could have easily been fixed leads me to ask “Who tested this modification for bugs?”.

    Comic Strips:I like this perspective of the modification rather then traditional cut-scenes.

    Generic:Using Wide-screen doesn’t make a modification cinematic in any sense infact that should be more of an option if the player wants to play the modification in either wide-screen or full-screen.

    Cut-Scenes:You never show the cross-hairs in a cut-scene or when essential dialogue is present. That’s a terrible way to introduce crucial plot to the player and over-shadow the story-line.

    Random Spawning:Not all, but some of the levels you literally spawn in a random area in the map.

    Ending Battle Was Simple:The ending was really just filler! I didn’t feel accomplished killing a weak N.P.C. to achieve the goal that was given.

    Over Used Models And Useless N.P.C.’s:In one of the levels you fight a Strider, and there is a Medic who literally does nothing. He won’t even attempt to heal you, and the N.P.C.’s literally block you at every turn.
