New Underwater RTS Subsiege Focuses on Intense, 12-Player Battles

Set in the near future of 2063, natural resources have been entirely depleted on the surface world, forcing humanity to dive under the ocean and seek out the last remaining resources.

Here are the game’s key features:

  • Hero-like squads
    Freely assemble your squad’s ability loadout and snipe your opponents’ ability casters to foil their strategy. Coordinate the squad set ups in your team and freely define team roles which work for you!
  • Merciless struggle for oxygen
    Survive unstoppable oxygen depletion and hunt down your foes to steal their vital oxygen. No hiding, no defensive play – fast-paced struggle for survival action only!
  • Teamwork above all
    Team up with a friend, contrive your unique battle plan and outplay your enemies. With shared oxygen reservoirs, resources and bases, seamless coordination and team work is crucial.
  • Massive 12 player battles
    Dominate the 12-player mosh pit, master your squad composition and ability timing and crush multiple rivals in one ingenious strike.
  • Deadly environment
    Counter surprise attacks of insidious sea creatures and trap your enemies above merciless deep sea worms. Watching your foes being badly ripped apart never felt better!
  • Underwater paradise
    Submerge into a fantastic underwater scenery, fight in between stunning illuminated corals and experience a lively underwater world with huge fish swarms, colorful reefs, thick black smoker clouds and steep cliffs.

Set for a release sometime in March of next year on Steam Early Access, the game’s developers pledge the game is “already fully playable, balanced, and generally free of bugs,” however they make the point that they are “constantly developing and improving the game.” To this end, over 20,000 players have been enjoying it at Gamescom 2015 and Gamescom 2016.

The game is planned to be in Early Access for roughly 6-12 months, which during this period the teams will constantly improve the game based on player feedback, with a focus on balancing and competitive play. Features they’re considering to add later include: more units, creeps, abilities, map features, advanced ladder and a highscore system, and more.

    Sounds more like another shitty hero moba – like than an actual rts.

  • Madbrainbox

    Depending on the number of units you control this can work.But a 12 player mode in an RTS?That sounds chaotic at best.

  • Meittimies

    Eh, not really a fan of RTSses with small squad sizes. It was still bearable in Warcraft 3 but C&C4 was awful, not to mention how they ruined Supreme Commander 2 with their “less units”-design.

    looks pretty nice

    That’s what it sounded like to me, the whole we were forced to liver underwater because of climate disaster when there isn’t enough water to melt to force us to do that, also is a good indicator of this games lack of quality.
