I was thinking that would be cool if Crowbar Collective added the scientist on Kleiner’s portrait from Half-Life 2 to the game, spawning alongside with the ones we already have (or replacing some). Preferably the short female and the Einstein looking guy, there can’t be a science themed enviroment without the Einstein scientist, not to mention that was one of the most memorables NPCs from Half-Life 1 (at least for me) and having him back will make the experience more “faithfull” to the original game. Also the rest of the scientist will be a cool reference to Half-Life 2 and a chance to enrich the Half-Life canon arc.

Just a small suggestion and please forgive my bad English.
PS: Don’t know who is the guy on the right. Probably Gman?
