It sounds/looks like Call of Duty as Melee though, nothing innovative, creative or persistent, unless you think persistent means unlocking achievements and abilities by playing (grinding) all the time.
No doubt it would attract more people to 'Melee games' though - which can be both good and bad in the long run.
I like games where I can effect the World I play in, such as Strategus. I don't like being a pawn in a story that's directed towards one self via the game but in reality everyone is playing through the exact same story. Nah, gimme a game where I can decide what I do and how my story should really be, tons of games preach that; forge your own story and so on but the only actual change is that your scripted path reaches a bunch of fork roads leaving you with more scripted paths to chose from, big wooptidoo.
More sandbox, more freedom, more players.
No doubt need to check this game out once it's available though
