- CF China: Biochemical Terminator Mode.
- No other versions yet.
Similar to the Parasite Expansion, this map option is mostly based on the classic Hero Mode X. It has unique mechanics found in Hero Mode X, but also features some from the other Mutation Mode variations.
Xeno still joins the battle to beat the soldiers. He still has the ability to use his Bulletproof Shield, but now he only takes 300 HP to use it instead of 500 HP like before. His default health point also got increased (9000 HP for Level 2, and 12000 HP for Level 3).
During the round, Xeno can pick the blazing Evil Box dropped on the map, and transform into Evil Terminator. At this time, his health point reaches up to 13000 HP. He can't use the shield anymore as the Fireball skill has taken its place. The Fireball skill allows him to form a fireball on his hand, the more time it is formed, the bigger and heavier it will gets. Its exploding radius depends on the fireball's size. When thrown, the fireball's movement speed is very slow; therefore, soldiers have enough time to detect it and avoid from fatal death. Any soldier that killed by the fireball will die and respawn as mutant immediately.
For normal mutants, they also have faster health recovery. Like Mutation Knight Mode, they can pick the new black Supply Boxes dropped around the map. When defeated, mutants still save both Evolution Level and Evolution Point when respawned. When evolved to Level 3, mutants are able to pick the Evil Box to transform into Evil Terminator.
Commando is also in the battle to fight against Xeno; however, he got some disadvantages. His health point is lower than before as he only has 5500 HP and his Dual Kukri also deals lower damage against mutants. To make up for that, he can pick up the freezing Hero Boxes dropped on the map and help him transform into Master Hero. His health point got up to 15000 HP, which is higher than any previous special characters. He is now wielding the Master Hero Saber to attack the mutants (which looks same to the Dual Daphne Saber). Beside that, he has the Rage attack with multiple slash, farther slash and increased movement speed. Commando will respawn as mutant after being defeat while Master Hero's death is permanent.
