I can not get past the first mission. I've tried three times now. I am playing solo because my ISP is total crap (and I don't have a choice of switching, only one in my area), and I can not play online multiplayer. I always get disconnects when ever I try with any game. Same with this, it sucks.
But yeah, I find this to be very hard on solo. After you kill the reactor and you start making your way to the exit, I just get ganged up on by like 12-18 dudes and they just annihilate me. Part of the issue is I am not finding enough ammo, so I end up having to melee them while trying to run past, and that never works. Ugh. I kinda like the game, but this experience is making me think I should just stop playing it. Maybe if I just keep trying and save up some of that XP I can eventually get past it.
