1v1 vs computer — YOUR lane (left) & the computer's lane (right), both live. Hold your Command Center; send creeps to crush the computer's.
How to play: the board is an L — build a wall on the first arm (tanks in front, DPS behind); creeps walk down it, turn the corner, and any leaks run to your King (Command Center). Fighters that die are down until the wave ends — your army resets to full HP each wave. 1v1 vs the computer: it plays its own lane on the right — watch it build, hold, and leak. Hold your Command Center (you lose if it dies) and destroy the computer's (or survive 30 waves). Minerals build fighters; gas accrues over time (boost with a Refinery) and funds the greed-vs-safety choice: Send a creep at the enemy — it grows your income and appears in their lane (cheap = eco, strong = pressure); the enemy sends back. Infuse hardens your CC. Match your damage type to the wave's armor (piercing→light, normal→armored, magic→boss — see the Data tab). Some waves are air (need dps/splash).
