In an upcoming update this November the PC version of Frontlines: Fuel of War will receive the additional Xbox 360 DLC for free in the 1.3.0 patch.
The content will include four new maps for the online shooter and will sport two new jet vehicles, one for either side. It'll have one new weapon as well.
The four new maps included are Hindsight, Sunder, Wide Awake and Infiltration. The new jet vehicles are bombers which will most likely be made short work of by the inclusion of a new anti-air missile launcher.
Frontlines: Fuel of War forces players to fight across 'frontlines' in order to push back and advance against their foes as sneaking behind enemy lines to try and capture a command position won't work.
The update is due next month.
