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.
Here you can see *a lot* of new things. The new HUD/interface which is much more in-line with the game theme. The new real-time lighting system (which can slow down the game on weaker PCs) adds a lot to the overall atmosphere of the title and the tile marks which accompany the updated control scheme are much more clear and legible.
