Get 3 guys to join your team and you 
will be fine, one will be the Sniper (AWP), 
the other the assault rifleman (AK47) and 
the last one will use the submachinegun (P90), 
another one could be the grenadier and 
simply use his handgun or the other p90 
in the zone...
Notes: stay cover and try to shoot 
through the glass with any of your guns 
couse the P90, AK and AWP can penetrate 
tin walls...
