Finally beat this! I started playing Dead Space back in December, but due to a variety of reasons (vacation, etc.) I stopped playing right around chapter 4-5. Finally got back into it last week, finished it, and man I can't wait for Dead Space 2 next year!
Before playing it I really wondered how it could possibly differentiate itself from other survival/horror/etc. games, but the low-grav, 0-oxygen, and other elements kept it quite nicely varied. Especially when you have to plant the beacon on the asteroid, and break the two tethers outside in addition to the two inside - sooooooo intense.
My main gripe though is that the game inherently forces you into use just a single core set of weapons. Power nodes are too sparse and too expensive for it to be worthwhile upgrading more than just a few items, and it's even more unweildy since you have to find a shop to swap out the weapons you're using. I stuck with the Ripper, Contact Bean, Plasma Cutter, and Line Gun. Would any of the others have been better to use? Because there would've been little to no chance to upgrade them if I did sad
I also encountered a few major glitches late in the game, but these only happened after I installed it to the hard drive - maybe that's related?
-Pickups always only pop up for the weapons in your inventory. Yet I occasionally got Pulse ammo, yet no ammo for other weapons. No biggie, but kinda weird
-The game completely froze once when I was doing a 0-gravity jump. The game continued rendering in 3D, sounds still played, but I couldn't do anything else. Had to restart from my last save
-The boss at the end of chapter 11 - the one that regenerates and you need to kill with a shuttle test fire - had really odd circumstances. When you kill that boss, all the other enemies are supposed to flee in fear. Well, one enemy couldn't quite find his exit point - a vent in the ceiling - so he kept running in a circle like mad! I couldn't kill him, he didn't attack me....he just ran and ran and ran. I gave him a little nudge out of the way, and he was finally able to make it up his exit laugh
-The last save point before the final boss is horrible. I saved as I was moving the Marker, but when I left the game and re-loaded, the marker was in the completely wrong spot. The game then actually let me open one of those airlocks before the marker was in it, making it impossible to proceed since I couldn't go back to get the Marker. Then I reloaded my game, actually moved the marker into the airlock, but since it was already glitched, it then wouldn't let me move the marker out of the airlock! Really weird. Had to go back to an early save point 30 minutes previous, really annoying.
