one thing I would have loved, even though I can understand games are getting more multiplayer based, is that there were more achievements based on single player or maybe even something like LAN play.
What I want to know is are the single player upgrades going to be made available in multiplayer games once Chapter 3 is released and all three factions have their fare share of upgrades. I'm sure balancing issues would be rife but it would be so cool though, and would really personalise one's play style a lot more. Just my two cents.
