In the base, the player can research new technologies in the labs and produce new equipment in the armories.


The enemies are more frequently mutants, but there are also plenty of missions that pit the player's PMC against rival PMCs (including other players' bases), criminal gangs, Alliance or Union forces, and aliens. The missions can be a part of a Story Arc or randomized. You send a squad of mercs (scouts, heavies, and snipers) on various missions to these territories. The world is split up into territories (blue, red, or neutral). The player is put in charge of one such PMC with an Elaborate Underground Base that can be expanded as needed. The delicate state of peace is maintained by the World Council, who oversee everything (literally) from their Space Station in orbit. The Union boasts a large, well-equipped standing army, while the Alliance tends to rely more on the large number of Private Military Contractors that have sprung up following the crisis. The two entities exist in a state not unlike the old Cold War. In the resultant Crapsack World, two power blocs are formed, similar to the old Cold War: the libertarian and economic North Atlantic Defense Alliance (blue) and the totalitarian, industrial, and scientific Red Dragon Union (red). Survivors live in heavily fortified and shielded megacities. As animals mutate into dangerous monstrosities, humanity comes under siege, unprepared for nature turning against us. The rapidly-spreading advinite proves to be a valuable resource, but its unique radiation has proven to be dangerous to living things, mutating terrestrial life forms into unrecognizable shapes. In 2040, a meteorite delivers a strange blue mineral to Earth dubbed "Advinite". The style of the game is heavily reminiscent of XCOM: Enemy Unknown, although the setting is more akin to Command & Conquer or Defiance. The game has since been ported to Windows. Mercs of Boom (originally called X-Mercs or X-Mercs: Invasion) is a freemium Turn-Based Tactics game, developed in 2015 for iOS by Game Insight.
