I spent about 15 hours on this already, and luckily for me, I only ran into one major bug (froze but thankfully game autosaved a lot) and one light one (two enemies in one spot). We played online two people with two characters each and it was fun and worked great, we only controlled our own characters. Sounds like maybe it’s more optimized for online than couch co-op, but who wants to buy two copies of the game if you don’t have to?
Music is improved, couldn’t play a lot of the first one because it kept making my partner pass out, too sleepy vibe. No issues like that here, soundtrack is nice.
I suppose it is really similar to the first, except the new taller models and stuff. The dead heroes thing seems new to and possibly neat, but I could be wrong. I see it more as a story sequel than a game sequel currently. I was happy buying it early, but for others, I’d probably recommend getting it on more of a sale.
