Mental Omega Wiki

Ultimate Alliance is a game mode where all players are given all 4 MCVs that unlock techs from all subfactions of their corresponding side like in the Unholy Alliance mode. In addition, all standard stolen tech units are unlocked by the economy booster of their corresponding side. As a result, there are almost no differences between any subfactions in gameplay, with the Engineer being a notable exception.

Ultimate Alliance mode shares maps with standard mode.


  • All 4 MCVs, GI, Conscript, Initiate and Knightframe will be given to all subfaction players from the start.
  • All subfaction-exclusive arsenals becomes available for all subfactions. For example Lasher Tank, Mantis Tank and Opus Tank is available at the same time with an Epsilon War Factory (even a captured one).
  • Both 'basic' and 'upgraded' version of units are available, for example Borillo and Armadillo.
  • All stolen tech units are unlocked by the faction's eco-booster structure and no need to infiltrate enemy buildings to use.
  • Allicon.png Mercury Network Uplink, Shield Command and Robot Ops Control Center's price decreased from $1500 to $1000. Power cost decreased from 100 to 50.
  • Sovicon.png Palace, Battle Lab and Atomheart's price decreased from $5000 to $2500. Power cost decreased from 300 to 200.
  • Yuricon.png Pandora Hub's price decreased from $1800 to $1400, its plugins' price decreased from $3000 to $1000. Plugins' power cost decreased from 200 to 150.
  • Foeicon.png Foehn tier 3 access expansions' price decreased from $1500 to $1000. Power cost decreased from 150 to 100.
  • Neutralicon.png Tech Secret Labs replaced with Tech Nuclear Plants.
  • Infiltrating Construction Yards and tier 3 access structures disallowed.
  • AI may attack with combined forces from all three subfactions including stolen tech units. Epsilon AI will build three Pandora Hubs to fully expand the tech tree.
  • 'Mental AI Boost' option force-disabled.


In this mode, like the Unholy Alliance mode, since the player can directly access all tech except the Cyborg Commando, it is possible to attack/ defend by combined units from various factions. Multiple types of IFVs is the markable example. Access of stolen tech units is also an opportunity in the gameplay.

However, initially holding 4 MCVs will bring two problems to players: First, players need a lot of resources to develop complete all factions' technology; Second, it will take a long time to develop complete tech of all factions, and players need to consider the development order of four tech trees. Also player should note that the enemy AI will use stolen tech units against you as well.
