hi all, i'm currently one of the unlucky ones who stayed up all night with my friends, then found out we couldn't play online together (yes, we tried port forwarding, so iunno what the problem was, however, now that online is working, it's so laggy we can't play it anyway) now i had rolled the gunzerker, becasue my friend dibbs'd the commando before i could. i've had alot of trouble getting through this game solo, the bosses are freaking impossible, i run out of bullets before i can kill them, my friends have encountered... similar problems, however, they have skills to help them compensate, a turret/turning invisable. as the gunzerker i can only shoot more, not helping the no ammo problem.
However i digress. Dr.mercy is a mini boss so no spoilers but, he carries with him, a massive shield, and a pistol that i reckon shoots eruidium (can take my shields out and hp down is a few hits) he basically takes very little damage from the front, and doing him solo means he will only face you, i also, run out of ammo before i can kill him. I was making progress, just using my brain a tad, kiting him. Then he starts throwing grenades, i sprint and jump out of the way, get him anyway, die.
try again, learn that his grenades are homing.
i litrially cannot get pass this boss solo, he was clearly designed for multi-player, which i also cannot do.
