Outbreak Tap
Watch your survivor auto-fire into the horde while you tap falling loot chests to choose gear, grenades, and upgrade paths between waves.
Combat is auto; your input is sequencing chest openings during the 5-wave run, picking which rarity to equip and when to spend cash on the 16-upgrade tree.
One-thumb tap on chests as they fall, swipe between gear slots to swap mid-wave.
