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.
