This is the final boss fight and the ending to the Half Life 2 mod, Research and Development. This mod only came out recently and is based upon solving puzzles, and I think it's one of the best singleplayer HL2 mods out there. I urge you to download it right now:

  • Don't do that. Use the command ent_fire ui deactivate when yo uget out.

  • same thing happens to me, i just stopped playing the game cause of it. its annoying.

  • I love this mod but I'm having a problem with Mr. Whirly. When I try to get out of the vehicle I become stuck and can't move. Can anyone help?

  • It is fun.. The best part is when you do the puzzle to get the gravity gun, the hardest is the runaway train puzzle, you'll know what i mean if you play.

  • dammit do i really need episode 2 to play this?

  • mr. whirly ftw !
