Single Player First Person Shooter Maps and Mods for Half-Life 1, 2 and Episodes 1, 2 and 3

Research and Development is a puzzle-centric mod for Half-Life 2: Episode Two featuring an unarmed player but plenty of violent mayhem.

The player has NO weapons and there is no shooting at all. However that doesn’t mean you can’t kill things, but 95% of the mod is about solving the puzzles that are presented to you in a very natural way.

Important Note

When using the keypad buttons in this mod, position the ‘finger’ cursor over the desired numeral and then ‘use’ it [E key] to activate the keypad button. Left-mouse-click will not work.

When exiting “Mr. Whirly”, if you get stuck so that your movement keys are still controlling “Mr. Whirly” even though you are outside of it, activate the console and type ent_fire ui deactivate + enter. This will restore normal movement control. For convenience whilst playing, this function can be bound to a key (e.g. “p”) by typing into the console bind p “ent_fire ui deactivate” + enter. (Include the speechmarks.)

    This mod has a good length, A variety of different tasks to complete (Mainly Puzzles) and all the scenarios and playstyles are different. It is great fun all the way through, Quite challenging at times too, but I managed to complete the whole game without any help.

    Pros:

    -Great Scenarios
    -Challenging Puzzles
    -Lots of different things to do
    -Quite long

    Cons:
    -Can be very tedious at times (

    Spoiler:
    Barnacles and Fuses…

    )
    -a few small bugs

  2. Personal Favourite

    This game is a perfect marriage of Portal-style game play and Half-Life 2 aesthetics.

    It is extremely enjoyable.

    The puzzles are very well constructed, and don’t rely on mindless wandering and nitpicking in order to solve. Logic and good observation are what are required.

    The way action is incorporated is fairly brilliant. The “combat” sequences were really satisfying both viscerally and intellectually. I felt satisfied I had figured out the puzzle, and enjoyed blowing up some assholes at the same time.

    Part of the reason this mod is among my very favorites, is because it’s so unique. The only other mod that I think comes close to this kind of game play is the Sprucecape Map Pack. And I find that pretty unfortunate. I would love to have more mods like this one.

    What’s going on!!, I haven’t reviewed this yet too!!!, thanks god and Phillip mostly for his absolutely brilliant mod-map matrix idea!! that i’m here.

    Well what can not tell you about this?!!, heck not many things. THIS IS JUST DEFINITELY A CLASSIC IN HL2 MODDING HISTORY. So that means you MUST play this one in order to turn yourself into a decent HL MOd gamer.

    Yep, this is a classic because its gameplay and dynamic plto is just brilliant, very very inovative,. entretaned and fun just using the GRAVGUN!, I know ther have been attempts to run some map competitions centered into the exclusive use of the gravgun, but excuse me, I think in my opinion ALL have failed, thers simply nothing best with the gravgun as main tool-weapon, than the maps you will face here in R&D.

    the textures are amazing along with terrific light effects, and i’m telling you I played this master piece about 3 years ago!!, so yep this is a special mod you can hardly forget.

    So come on you MUST PLAY this amazing classic mod.

    Can I add a PF every time I play it?

    1. Only if you suffer from a particular type of amnesia called “Modulitus”.

    Hi Phillip,
    Just to let you know that the download link to Gamesmodding gives a “website not found” error while the one for FileFront (Gamefront) gives a “page not found” error.
    Cheers

    1. Link now updated to current version.

  7. Yohan

    The download for this mod is missing.

    1. Link now updated to current version.

  8. I have a problem in Chapter 2, entering the code digits into the keypad to get the energy cube.
    NB: this is NOT the well-known old problem, where the wrong buttons were being pressed by mistake (which was solved by “crosshair 1″)
    I have the newest version, with crosshairs AND “finger-cursor” when I approach the keypad.
    No matter where or how I press, NOTHING lights up – not the “ring” around the button digit, not the coloured lights above the keypad. Nothing. It is as if the mouse button clicks are being completely ignored.
    I am running Windows 7, 64-bit.
    Additional info:
    The console is frantically scrolling this message:

    Material models/magnusson_teleporter/magnusson_teleporter_fxglow1 does not support vertex format used by the mesh (maybe missing fields or mismatched vertex compression?), mesh will not be rendered. Grab a programmer!

    If anyone has any ideas, please share them. I cannot progress any further into the game.

    1. I suspect the error is due to an update from Steam and not your or the mod’s fault. Maybe a reader can offer more helpful advice.

    2. Since this mod worked perfectly for me a couple of months ago, I started by writing a rude reply about Valve’s continued mod vandalism. Then I figured I would try and give weapon_gravgren (which is what the energy cube effect is based on, I’m almost certain), and then I made an embarrassing discovery.

      You don’t click on the buttons, you “use” them (E) and they work fine.

      “Ahem.” Oops..

      Still, at least it’s not been broken (yet)! Happy R&Ding

      1. TrevorMag

        Thank you very much Sparks. I’ll confirm it tonight, but I’m sure you’ve nailed it.
        I’m 25% embarrassed, but not a single percentage point more: the way the mouse cursor turns into a finger is more than a “hint” to press the mouse button – it’s hardcore blatant. Still, the rest of the mod is awesome, but a one-person show can’t afford level of QA and play testing that the major studios can.

        1. Agreed. I read that the “finger” cursor was an addition after people complained that the cursor wasn’t clear enough and/or they ended up pressing random buttons by mistake, but it is still a bit counter intuitive though. I meant I was embarrassed as I’d played it through recently, and forgotten that point already!

          Yes, it’s an excellent mod (must be high on Gabe’s “Break It!!” list) but I will warn you that there’s an extremely difficult/frustrating bit coming up where you have to to MANY things simultaneously. I won’t spoil it, but it involves a train cart ride. Quick save like mad here; literally all the time, but do persevere through it as it calms down immediately after and becomes fun again.

  9. Play It Now!

    Brilliantly made, but it became a bit of a chore. It felt like it needed some npc’s to carry the story along. As it is just feels like an endless grind, with no feeling of progession or how far through you are.

    Spoiler:
    Also some of the sections were horrible F9-fests: eg train section, and the helicopters. And on the subject of helicopters: doing it once was ok, even if it was ripped straight from ep2, but having to do the same thing again for the gunship, then again for another helicopter was tedious.

    Although I like puzzle games like Portal and Unmechanical, I felt this would have been much better with more traditional HL/HL2 gameplay – with a nice balance of the puzzles interspersed with combat , and exploration, all tacked together with a bit more story.

    1. Yes, the train section (specifically with the homing-zombines and simultaneous hail of insta-exploding grenades) was definitely a pain and a chore, as you say, constant quick-saving being mandatory. You make a good point about the lack of balance with not enough conventional HL2 content plus nasty difficulty spikes (like the train). It’s clear that the mod is a showcase for the clever mechanics, and whilst they are good, a better balance and consistent (or ramping) difficulty would have improved an already very good mod.
