The classes of strike force heroes 2 (except for the general) are a big improvement. The engineer is more on offensive than a medic. A mercenary is more like a one solid unit than a commando. A sniper has better survival skills than a assassin. A juggernaut is like a one-man fortress than a tank. Also, the slot machine is handy because you can buy items in a more cheaper price. the online saving is there, so worries 'bout resettin'.
