Oil Rush, one of the best looking games build so far on the Unigine engine and one of the most pleasant Linux surprises, can be bought now with a 75% discount. Oil Rush is a mix of strategy and tower defence, combined in such a way that it practically has no rival. It’s built on the famous Unigine engine, the same one used in Heaven DX11 Benchmark. The player assumes the role of Kevin, a young graduate from a military academy, who strives to follow his father’s example. He is immediately given a job to defend his colony from raiders’ attacks, and so his adventure begins. We reviewed Oil Rush a while ago and found that it’s worth every penny and that it’s one of the best Linux games launched so far. If you are interested in the 75% discount for the Linux version, you should check out gameolith.com. The deal will expire on December 17. via Softpedia
