Battlemass is a turn-based strategy game with both single-player and multi-player support. A match is played on a map consisting of tiles, and in turns of 3 phases – combat, harvest and build. The goal is to destroy your opponent's Base/City Unit. One of the cool features of the game is that you harvest the map/board's tiles for resources but in the process destroy the tiles, and any unit on such a tile.
I've made the FULL game of Battlemass FREE to play, so go grab the new version now.
Battlemass is a multiplayer ONLY game, so be sure to invite a friend to play a match against you if you can't find anyone online when you want to play. Remember that it is also possible to continue a match at a later stage, so you could easily join a match, take your turn and then login again later through the day or even the next day to check if your opponent took his turn.
