Colosseum: Half-Off Plus

One run of the Otherworld Colosseum (Special Stages): five Rounds at 200 energy each, No Continues, every enemy base over a million HP, played under one battle rule for the whole run — here Half-Off+: Special: Special-unit deploy costs are halved and their cooldowns shortened by 30%, and two units deploy at once. The wiki lists this as one of the two newest runs (rounds added August 2026); the rule actually in effect shows in the icon at the bottom-left of the stage select. Rounds 2–5 each unlock by clearing the one before. Needs A New Legend (Uncanny Legends) cleared.
