I watched the GameTrailers coop gameplay just now, and the more I see, the less I'm interested. Gameplay consisted of standing there shooting of a trillion rounds, as the medic healed the player so he didn't have to dodge. I couldn't sense any...gameplay! R1 had a lot of running, shooting, hiding, etc. Just standing there firing doesn't strike me as fun. Plus everyone getting in each other's way was annoying. The should have friendly fire to deter that. Not that that'd bother anyone, as the medic would just beam some heal on them.
Oh believe you me, it's some of the best fun ever! There's just so much depth in it I feel that you're not seeing right now. I once got into a group that was pretty good already, setting up different kinds of berzerk traps, and another time when I was going at it on my own, I was exploring the environment and found at least different routes to go at the enemy, one through houses, one through tunnels, one through a tube, one all the way round, and the default way over the bridge. So you can have someone sneak in, throw a few grenades, or god knows what.
Also, the depth in this game is partly in how the game scales for 2 players to 8 players. I got in a few different ones at the start (starting with 1, 3 and 5 and 7 players) and it's a wildly different affair. Right now, stupid AI or no, it's hard work staying alive and get very far, but it's a lot of fun and it does require at least half-decent cooperation, which is what it is all about. Basically, it feels like a pretty advanced version of what Gears has as the Horde mode, and it's a lot of fun to play, and there's a lot of depth in the environments.
I think that there aren't that many ways to do it differently - there are a huge amount of monsters when you're playing with higher numbers especially, and you can't have all of them come at you at once, so the difficulty is in making sure they come at you in the right kind of waves. The monsters that do come at you, do try to surround you, and you're being tricked into being surround very early on by the game level's design, which is pretty crazy and hectic.
You really have to try it to see what it's like.
I may be the only one who likes all the modes, but I loved Resistance's single player campaign, but could never get into the online stuff. But with the R2 Beta, I love all the modes, skirmish (60 player skirmish is awesome - sure there's room for more objectives, but there's a lot of room for strategy, and I love weapons like the Belkin that really offer some unique gameplay mechanics that aren't obvious or carry over that easily from other games like sniper rifles, which are much more accessible - I'm fairly adept with those). But even team deathmatch or the other modes I enjoy, the coop, and I'm sure I'll love the single-player campaign a fair bit too.
And I can't believe how good the netcode is, I've been playing with a large part U.S. people and it runs great even with 60 players from both Europe and the U.S.
I've offered patsu the beta code back, because it's too addictive and I can't spare the energy nor time! Too darn addictive.
