Destroy the world that feeds you in Greed Corp, a casual turn-based strategy game that plays similar to a RTS, but with a twist!
In Greed Corp the player is one of four possible factions fighting over a hex map with height. The basic idea is to gather resources, construct fighting units and defeat your enemies. The novel twist is that extracting resources undermines the land, lowering it in height. If the height of a hex falls too low, then it collapses - falling away into the mists along with anything on it, gone forever. In practice this means forces scurry across the map, leaving devastation in their wake before engaging the enemy on what little of the map remains. Initially the game works well.
Unfortunately the game often ends with one side clearly stronger, but the map denuded of resources. Thus the game descends to a slow grind, with one side destined for victory, but getting there at a lazy pace while gathering the scant remaining resources. Later missions in the campaign also have time limits on turn length, which I personally do not appreciate (if I wanted such a constraint I’d play a RTS!). Still the basics are enjoyable enough to keep a player entertained for several hours.
Greed Corp is out on the Steam store for PC only at US$9.99. It has been bundled many times.
