I'd say best positronic for snipes up to 1700 distance, type 1 stinger for distances 1700 and closer and high desity photon when the enemy is close and your out of ammo, but out of all i'd say stinger since postitronic gets useless soon on and stinger is best for homing on enemies and dealing very good damage
@NightandFaye, You are wrong, hotkeys exist to select weapons and to fire, and if you don't understand the game then don't play or LEARn, don't whine about you misunderstandings.
I love the proximity blaster, so if you have trouble with drone ambushes drive up to them and destroy them with your blast, and collect and ammo pack, so you can keep chucking them.
P.S. Try to clump them so you get more in one shot, and so you can kill more of them before your stupid AI partners get your target.
I listened to what you guys said and even when I lose my ten lives my stuff is lost and i log-in I'm still stuck with the human alliance, I want to be an Alien!
