So I just beat this for the first time. I'd played it when it first came out till about chapter 6, but then something else came out and this kind of got lost in the backlog. But since the sequel just came out, I decided to give this the full play through before I picked that up.
And oh my god it was fucking awesome. The tension in the first 3/4 of the game is so well done. I wasn't ever really scared per se, but there was a constant sense of impending doom. Then I got to the last couple of chapters, with my line gun and plasma cutter pretty much fully upgraded, and just totally tore things apart. I've had very few experiences in game that much up to the satisfaction of just mowing through the armies of necromorphs the game throws at you in the last couple chapters. Soo fucking good. And the contact beam was absolutely amazing to use as well. (Those were the only three guns I used the whole game plasma cutter, line gun, and contact beam.)
So I'm gushing over this, sorry. I'm still buzzing from that final boss fight. Can't fucking wait to get the second game, but I'm snowed in damnit. Probably should have started a LTTP thread for this but I figured there were most likely a ton of those for a game like this, and the OT had been active recently so I just used this.
