Battleforge, you might remember, is a “deck” based RTS, in which you play a pre-selection of units against your opponents. It went free-to-play a couple of months after launch and is now supported by people purchasing the expansion card decks. The Lost Souls expansion, which arrived last week, contains two new factions, which in turn delivers 120 new cards to your deck, adding 28 new units, 16 new buildings and 16 spells. The cost for a Lost Souls pack is about $2.50. The main game is free, and although not my favourite RTS experience it does have some neat touches and is probably worth trying out if you like a bit of strategic fantasy elf-biff.
