Steam is halving the price of Empire: Total War this week to celebrate the release of the Warpath Campaign expansion.
Empire: Total War, which we gave 9/10 to, now costs Ł14.99 from Valve's download service.
The Warpath Campaign sets you back a further Ł6, and adds a North American adventure to the mix. This opens a handful of Native American factions, each with their own tech and units - and challenges you to repel the invading Europeans. The Cherokee tribe and co. can be picked for multiplayer skirmishes, too.
There are other pieces of DLC to snap-up on Steam, should you wish, plus a Total War: Mega Pack with all the key releases from Medieval: Total War upwards.
