awsome, me like. just waiting for a key now
EDIT: May i ask what the difference between these game modes are, and how many game modes that has been confirmed?
Not sure if they've changed any of this, but
Competitive - what you are used to in CSS. Ammo is not purchaseable (in any game mode), kevlar and helmet is. Zeus (taser gun) is not available. Money system is almost like before, except for the weapon pay-offs.
Casual - kevlar and helmet is not purchaseable (you spawn with it), one person also spawns with a free defuse kit. Even if you lose or don't perform well, you earn nearly the same as the enemy. Eco rounds are pretty much gone
Arms Race - exactly as gun game
Demolition - round based gun game, extra kills per round only gets you a bonus grenade
