Here is a small hint if you want to know the three best guns. 1st gun is the isa assult rifle. 2nd The big chain gun. This gun launches missiles. #rd is the sniper rifle. Good for long range. Note: In the sniper place on the beach-head level, I called the chain gun a machine gun.
First get the sniper rifle and then get the big machine gun that also shoots missiles. Then at the ISA base the three big pipes coming out of that building you will find a path up. Go up all the way and there is a balcony, from there you can see almost everywhere. Note: enemies and allies will respond on floors of that building so every now and then get the machine gun and clear out the floors. This should help in Deathmatch, Team Deathmatch, Assult, and Defend and Destroy.
