The movement controls for this game are something to get used to but ones you do it is a standard survival shooter you play in 3 different difficulty levels.
You have to survive several waves of enemies which each wave adding more difficult enemies.
Your character has special skill you can keep switching between, from throwing objects, using a shield, throwing fireballs and more.
In addition in each room you have objects which can temporarily help you defeat the enemies such as turrets, shield barriers, explosive barrels and more.
You can also temporarily take cover behind some objects but best is not to stand around to long on the same spot.
The game is quite fast paced in this regard. You have to keep moving, avoiding gun/sniper fire, grenades, and other enemy attacks while using your special skills and the environment to help you fight in this game.
The game is an average survival shooter type game with controls you need to get used to.
Achievements would be a nice addition to this game.
I still would recommend the game though as I don't think it is horrible but is quite fun for a while and surviving all waves without dying is actually not all that easy, the graphics are quite nice and the price does not seem to much for this game.
All in all I would give it 6/10 which in my books makes it still a recommendable game.
