Research and Development is a puzzle-centric mod for Half-Life 2: Episode Two featuring an unarmed player but plenty of violent mayhem.
The puzzles are brilliantly designed with a clear goal in mind! The lack of custom content didn't detriment my playing experience, and I simply loved this mod. The fact that you can kill things without a gun just makes it all the more better to see happen. You've really raised the bar with HL2 mods and, more importantly, your mods!
Im struggling against some bugs, i cant do some stuff like numpads (glow mesh missing sth...) but the idea behind the game is awesome and so are the puzzles, its a total ten because the bugs arent you're fault and if the game was on steam i wouldnt probably be having this trouble.
