Amazing but it ends before you know it :(
The game is about Eddie Riggs a Roadie how works for the worst Metal band in the world then he gets injured due to an accident in the stage and blood gets into his nickless and he transfers into a metal inspired world and he have to fight with human for their survival.
The game play style is a combination of Hack & slash RTS and sandbox game-play you recruit troops to fight with you to defeat your enemy, as you progress you will have more troops and units and it will feel like an RTS, what also great about this game is the funny great story-line which I wont spoil :).
There is also a lot of thing to unblock through the game like solos to help your army to give them boosts and such and also Concept arts and by completing the main & side mission you will earn Fire tributes which acts like the currency of the game which you can buy new moves and upgrade your weapons and you car.
the game though does have flaws like the repetitive side missions and the graphics are dated but the most disappointing thing is that the game is pretty short and you will feel bad for it to end so quickly.
