Finally get to play my own copy instead of camping at a friend's house. So late impressions:
1. Ugh, the save system is GODAWFUL. If this is the result of MP, then get rid of MP next time and give me a clever AI partner (ala RE6 AI) if you insist on shoehorning a partner.
2. I hate these people whose name is not Isaac. What a bunch of ungrateful fuckers. I wish I could have seen them getting tentacles up their asses while Isaac is somewhere else, having easy time dispatching other enemies. And yes, that includes Carver, a candidate for 2013 worst new character. This was a category won by Connor of AC3 last year.
3. The enemies are getting ridiculously fast but Isaac don't have similar change in speed to match them. The thing is, it's not even scary anymore to be jumped on like that. It's just annoying and you rarely can do a strategic dismemberment anymore. Plasma cutter is kind of useless here without stasis whereas before, you can pretty much rely on it even when there's no stasis nearby.
