Game 08 · Lane defense · 6 scenarios + Endless
Contain a spreading outbreak before it consumes your core.
Pick a scenario to begin.
Defend. Enemies advance along lanes toward your core. Tap or click an enemy to hit it - most take several hits to destroy. If an enemy reaches your core, it deals damage equal to whatever health it has left.
Waves. Each wave spawns more enemies, with more health and speed than the last. Clear every enemy in a wave and the next one begins automatically.
Boss waves. Every 5th wave (wave 5, 10, 15...) brings a single armored boss with a large health bar alongside the regular spawns. Starting at wave 10, bosses cycle through four distinct kinds with their own attack pattern - not just more HP:
• Variant (wave 5, 25...) - baseline: high HP, slow advance. • Broodmother (wave 10, 30...) - splits into two fast spawnlings the instant it drops to 50% HP. • Ravager (wave 15, 35...) - periodically flashes a brief telegraph, then dashes forward at over 4x speed. • Warden (wave 20, 40...) - periodically raises an invulnerable shield (glowing cyan ring) that blocks all hits until it drops.
Pickups. Defeated enemies have a chance to drop a collectible token that sits in the lane until tapped (or it expires after 6s). A Damage Vial (orange, ⚔) grants +8 damage per hit for 8 seconds, stacking up to 16s. An Overcharge Cell (gold, ⚡) banks one free area blast, usable even while the blast is on cooldown, for 20 seconds. Boss kills always drop a pickup; regular kills have roughly a 1-in-6 chance.
Area blast. Once off cooldown, the blast instantly clears every enemy in your most crowded lane - save it for when a lane gets dangerously full. A banked Overcharge charge lets you use it a second time even mid-cooldown.
Scenarios. There are 6 numbered scenarios, each with its own starting core HP, lane count, and a target wave count shown in the progress bar. Reach the target wave with your core still standing and the scenario is cleared - you earn 1 to 3 stars based on how much core HP you have left, and the next scenario unlocks. If your core reaches 0 HP first, the scenario is failed - retry any time, no progress is lost.
Endless Outbreak. Clear all 6 scenarios to unlock this open-ended mode: waves keep escalating forever with no target - survive as many as you can for the highest score.
Win condition: reach a scenario's target wave with core HP above 0. Lose condition: core HP reaches 0. Your run summary reports enemies destroyed, bosses defeated, pickups collected, and your longest streak without taking core damage.
Clear a scenario's target wave to unlock the next one. Stars reward how much core HP you have left when you clear it.
