Funny but not great...
First of all the game is really funny and give you enough freedom to make incredible movements. Jump, fly, climb, run fast, grab, hit, shake the ground, destroy objects, drive vehicles, use guns, change appearance, ... You can climb all the buildings and stroll the city freely. Objectives are not too much hard to do but some side quests are really difficult. You should upgrade your abilities. Graphics are not the best but enough and don't force the PC. But some bugs cause crashes.
Thus far everything seems OK. The game is really funny but there is nothing more except upgrades. Actually there is not a real story. The character tries to find his past. When he gets an objective he goes somewhere and kill some creatures and humans. A new objective comes as the same like the before one. Go somewhere and kill something. There is not any puzzles, not any different scenario, almost no aim, no intelligence and no creativity,...
I give the game above an average point because it is really funny and has a great playability. With good story and different enemy levels with bosses (and maybe some puzzles) the game should be better.
