Thing-Thing Arena
The Thing-Thing spin-off: instead of a story mode, a drop-in arena where the series' gunplay becomes a straight fight for survival. Weasel took the run-and-gun feel of the main series and set it in closed arenas -- pick your weapons, stay moving, and last as long as the enemies let you. Kongregate's page counted 60,098 gameplays, 4,154 ratings and 563 favourites by early 2009. Move with the arrow keys, aim and fire with the mouse, and use the arena's cover.
