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: place tanks in front, DPS behind — creeps walk straight down your lane and fight your units (a unit that dies is down until the wave ends — your army resets to full HP each wave). 1v1 vs the computer: the computer plays its own lane on the right — you can 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 & tech; 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 at you. Infuse strengthens your own CC. Match your damage type to the wave's armor (piercing→light, normal→armored, magic→boss — see the Data tab's matrix). Some waves are air (need dps/splash). Mechanics are in docs/ENCYCLOPEDIA.md; code walkthrough in docs/CODE.md.
