i got to the part where there was a 3 leg alien coming out of the ground trying to claw the heck out of me and you had to distract him, i turned on that generator, then i did a couple of bad game saves after being too lazy and at that point i didn't really care
ah, i remember that dude. he could hear you, so you had to walk so you didn't make noise. and you could stun him with some grenades.
i feel your pain on screwing up saved games tho.
