I just finished the single player campaign for Resistance 2, and let me tell you, it was infuriatingly difficult. I died at least 20 times in each level, which is a huge amount, and I was only playing on 'medium'. I might, MIGHT attempt a 'difficult' run, but I don't know. It was just so frickin'... trial by getting shot. It was fun, though. Really fun. Interesting guns and you get psychic powers for the last 4 minutes of the game.

The multiplayer co-op is brilliant. You choose to be 1 of 3 classes (Soldier - tank, Medic - medic, Spec ops - ammo guys) when you choose a game. Each game is up to 8 people, 8 maps total. The missions take place about a year prior to Resistance 2, and your guys are given randomized objectives out of a pool based on the map, so no 2 games play exactly alike. Every point of damage you deal give you EXP, which levels up your class, up to level 30. Every couple of levels, you unlock a new secondary weapon, and every couple of levels, you qualify to upgrade your equipment with 'gray-tech', in game items found from defeating the boss or sub bosses in each level. Every time you play a level, you get a different piece of intel based on the map you're playing. Some maps have 8, some have 12, which encourages multiple plays to learn all about what you're doing and the back story of the game. It was interesting to hear Specter Team, your 'group', referenced in the main game -- as it turns out, you're doing something integral to the destruction of the chimerans after all, and not just running around like chickens sans heads.

Communication is a must. The soldiers have shields they can deploy, but drain secondary ammo, so it's good to have a spec-ops near by. Other players can hide behind the shields while soldiers fire away with their primary weapons, the chain-gun (called The Wraith) in game. The spec-ops have scoped weapons and are more headshot proficient, while the medics have no acceptable form of direct attack - they drain HP from enemies and convert this into healing energy to heal squadmates.

I've logged around 10 hours into it, and I have a level 10 solider, level 3 medic (after 1 match, the EXP they gain is redonk) and a level 1 spec ops.

Of course, this doesn't touch on the competitive multiplayer, with squad based 60 player maps that are lag free so far. Plus a fun little skirmish mode that has players competing for the same objective.

It's really a great game.

... Way better than Bioshock.

Anyone else play? PS3 only.
