Deadly Games was a sequel to the original Jagged Alliance. Unlike Jagged Alliance 2, however, it had a different format from Jagged Alliance and therefore was considered more of a spin off than a sequel.

In Deadly Games you take a group of mercenaries (mercs) through a series of missions. The missions are ordered but they are not geographically linked as in Jagged Alliance or Jagged Alliance 2. The most innovative aspects of Deadly Games include a wide variety of mission types, new weapons, multiplayer, and scenario and campaign editors.
