Download Avert Fate
Avert Fate was launched in 2008 and despite being just a freeware game, it has marvellous graphics that you will definitely enjoy as soon as you start playing. The visual effects are also nicely done and you will enjoy every second of the battles, even if they take place at a high pace.
The game is nicely designed in order for you to have a great experience as you try to destroy the robots of Doom, an army of high powered machines that will stop at nothing, besides you. Avert Fate also has a great physics engine that will bring in more visual effects.
