First let me say, I didn't try multiplayer, so this review is the campaign alone. It was a decent enough storyline, with ok characters. The gameplay was fun enough, with 4 characters which you can jump to at any point, each with different weapons and skills. Overall, it felt like a solid game, but it was just not...great.
There were only a few enemy types, so you just keep mowing down the same bad guys. The weapon selection is EXTREMELY limited, with no upgrades. This seems like a game which is more fun if you are playing with friends. But all said and done, there aren't any huge glitches, and it's relatively fun to get through. I'd say it's worth renting, just don't expect some grand storyline or gameplay.
Each Game I rent I sit with a notebook and make notes along the way. Here are my notes from Fuse.
Overall a very fun game.
Like being able to switch between 4 people.
Controls are very easy to use
Tip Reminders throughout playing make it fun to play
LOTS of shooting
Team AI actually help instead of just standing around
Good blood splatter and graphics
Auto switch shoulder with weapons makes for easier shooting
Movement is like Army of 2 only easier and faster
Good cut scenes
Being able to save eachother and all 4 have to die to have to restart
Very neat storyline and easy to follow
Bosses are perfect challenge level
Stealth kills are cool and there are multiple hand to hand finishes
High replay value
Good level variety
Good diversity in weapons
Good enemy diversity but don't get too hard that you give up
Good locations where there are additional rooms with nothing in them so you have to actually look for the extras
Realistic shot damage
Good sliding and getting into coverage.
Unrealistic enemy sighting. You can be in plain sight and enemy still doesn't see you
Instant replay would be a cool feature
Can't customize weapons
Not very many weapon choices, diversity but limited choices
