No Mercy seems crazier here than it was in RE5. I got stuck between two giant waves of zombies on a staircase in Urban Chaos and had to spam flash grenages, melee, and herbs to get out. Then I turned around and shot a RPG at the other side lol.
What they need to work on is consolidating matchmaking. This game has co-op (4 campaigns with 5 chapters), agent hunt (12 scenarios in this, but it isn't too hard to manage), Mercenaries, Mercenaries No Mercy, Onslaught, Predator, Survivors, and Siege (the last three are not released yet on PC). On top of this you can't specifically look to join campaign crossovers and those become increasingly rare to get to work (the console launch had enough dudes where it could realistically happen, but not with the PC release it seems).
Oh yeah, it is annoying they didn't remove the search result limit for PC. I kind of wished they just gave me a big old server list for all the game types. Failing that, the ability to have my Mercenaries game interrupted to do something I like... I'm thinking being pulled into campaign crossovers.
