What makes you think this new vehicle from single player is going to even be in multiplayer?
Considering there is no multiplayer for Episode 2 that would be kinda difficult. And Batman dont try and claim TF2 as being EP2 MP...because we all know it is not. Completely different games, weapons and art direction.
Half-Life is all about Multiplayer? Show me please. There is Half-Life DM, and Half-Life 2 DM...incase you havent looked lately, but HL2DM is all but dead. Once upon a time HLDM was popular, but it certainly didnt make Half-Life single player popular by any means. CSS, DoDs, TF2....all seperate entities, based on different worlds and are not part of the HL2 universe.
So NO, multiplayer is not all this series is about, infact it has nothing to do with the single player games sucess at all.
Someone please help Batmans remove his head from his ass.
