Co-Op Mutation #255: Growing Threat

Amon's forces have been altered by the terrazine on Bel'shir in unexpected ways. Increased adrenaline triggers unpredictable transformations and each new death unleashes new hostile forms. The most powerful of them have even developed nuclear capabilities.

Map: Mist Opportunities

Enemy units have a chance to transform into more powerful units whenever they deal damage.
Mutually Assured Destruction

  • Whenever an enemy kills one of your units, it transforms. Avoid losing ANYTHING whenever possible.
  • Enemies transform into tiers based on the supply of the units they kill. An enemy that kills a Zealot (2 supply) will level two tiers.
  • Units have a chance to transform into Hybrid. And those ALSO detonate nukes.
  • Hybrid nukes detonate INSTANTLY after the death animation. Yep.
  • Alien Incubation spawns a number of broodlings proportionate to the slain unit's supply cost.
  • Spawned broodlings can transform into units.
  • Enemy units, upon transforming, return to full health. Make sure to focus the strong ones before they become Hybrid.
  • The enemy is really effective at clearing out spider mines now. If you want to use them, make sure to place them at the exact spawn points, rather than the pathing. Alternatively, add ranged units to draw aggro away from the mines.
  • The broodlings sometimes wander into your expansions and transform up to hybrid as they kill workers. It's a good idea to have some form of static defense or have insanely fast reactions to avoid losing workers.
