my overall effect so far (i'm on Act 5):
campaign: took a shit on anything i expected and felt like i was just thrown into a completely new Gears game. i mean, i understand this is based 2 years after Gears 2, but still, i have yet to receive much of an explanation to anything going on. so there are lambent. they're taking over. woo. throughout the entire campaign i have been not knowing a damn thing about why they are there, how they came to be, etc. i mean i know you see lambent at the end of Gears 2, and that they come from emulsion, but i mean wtf? nothing besides that?
multiplayer: still bullshit, as always, but fun.
horde 2.0: FUCK YES. i play Horde for hours with friends and it's just so damn fun. it's not just killing anymore. it's killing, with upgrades!
my only problem is how aggressive everything is. i was being chased for god knows how long trying to get some headshots off for a challenge and the fuckin grub wouldnt get off my ass at all. annoyed me. big time.
