Monstro. A fully deterministic logic game which plays like a tactical RPG but without RP, character growth or randomness. Fight the opposing army on the battlefield, which just so happens to be made up of conveniently perfect squares. Survive the onslaught and strike back to be the last one standing. Or, occasionally, do something else the evil Skygods want to be done for their own amusement. It is like chess but the units have statistics and your opponent is noticeably dumber than the average grandmaster.
The latest trailer showcasing how the game looks and feels after all the updates done for Steam release, coming December 3, 2015.
