this is just my choices but im open to all others. endorsments i use X3 rof X2 critical X1 accuracy not only does that build pact a punch but asualt has a quick relode easy to mess people up in all stages of the game. for my ability i put the first 300 into assult and his bomb. upgrade the assult class all the way first then contue to upgrade your bomb all the way as well. after both those are maxed then upgrade your charge all the way. i vary from map to map about his jetpack because only few maps can you save yourself from ringout with it or manover away from dieing. but this is just my build any of you have any other suggestions?
Keep Gold ROF if you use your Grenade Launcher a lot. The boost on the Assault Rifles isn't as noticeable.
