Strange powers tore Adeptus Mechanicus faction from Warhammer 40K universe (only planets and fleets that were fully under Adeptus Mechanicus were teleported, Void Dragon still in his prison and can’t help in any way). At the same time both new X-Com and old X-Com verses were teleported (X-Com from action games are not included, aliens untited with humans) and forced to join forces with Adeptus Mechanicus. And lastly mysterious powers teleported Kain‘s Empire along with planet from LOK (during events of SR, Raziel and Elder God are not included) and forced them to join forces with old guard alliance as well. Now they all must face another alliance in battle.
Strange powers teleprted both StarCraft (StarCraft vers is at the time of StarCraft 2, after Kerrigan became leader of Zerg again, but before Mengsk death, Amon not allowed)) and Destiny (for now Oryx is the only god who allowed for Destiny‘s side, all factions united of course) verses in order to force them to fight against several other faction.
Tech share is allowed, Kain or his vampires are not allowed to make new vampires from members of old guard alliance.
Who will win?
