There has been some Linux game updates and news in last week. Warzone 2100 has been updated to version 2.3.9 and is last release in 2.3 series. This release sees many bug fixes, some UI tweaks and translation updates. You can grab your copy from here.
Towns, a city building game inspired by Dwarf Fortress with roguelike gameplay elements will have a Linux version. The game is currently in alpha stages of development and looks very rough and unpolished at the moment. However, it seems promising though.
