Frontlines: Fuel of War is a military-themed infantry and vehicle based, open-world first person shooter. The newly formed Red Star Alliance, led by Russia and China, clash with Western Coalition (U.S. & the European Union) forces over increasing energy shortages. This sets the stage for a massive conventional apocalypse pitting the biggest military powers against each other as they try to defend their interests and support their collapsing economies.
It's got good graphics and gameplay is fun, but with the lack of servers and the need to download several gigs of patches I find it all the more worth it just to play battlefield 2.
