Sorry if this seems 'noobish' to some of you more advanced players, but I have two questions regarding siege mode and controls thereof. First of all, how does a tech do tech-specific functions? I know picking locks is easy enough, and I guess repairing stuff works the same way, but how do you refill health and ammo? Second question, how do you changed the clocks display? I've seen it counting up sometimes, counting down sometimes... Is there are button to control that?
Thanks for any help.
