Completely Broken and Unplayable.
First off was the training mission where they didn't tell me any controls and wanted to see my "experience" level so I managed to get passed the rocket jump area and didn't know what to do from there. I went into the advanced portal and the ai showed me what all of the powerups were for and told me we would have a battle to see how it went. I was expecting it to be alright because the game was pretty impressive so far.
This was not the case however. The bot continuously destroyed me because there was no way to move the reticle around. It lagged all around and kept stopping every inch or so I moved it. This made it impossible to hit anything yet the bot was still able to pull off constant hits against me and that was when I had had enough.
In short, while this game looks nice, the mechanics make it completely unplayable and a waste of a download.
Don't even waste your time.
