ZROI — Zombie ROI Unit

ZROI is not a controllable unit. Four separate outbreaks — Type I, II, III and IIII — bite your ROI Units for 1, 2, 3 and 4 Integrity and multiply daily inside their own Power pool (100 / 200 / 300 / 400). Eliminating exactly one zombie costs 0.39 / 0.66 / 0.93 / 1.20 Passive ROIP for Type I / II / III / IIII, and awards 1 / 2 / 3 / 4 Elimination Score on Leaderboard+. If a swarm can't fit its doubling inside its Power, it collapses back to a single zombie.
