Project Terra

A free browser tower defense. Open a tab, hold the line, close the tab. No install, no launcher, no account.Enemies push down from the north. You buy turrets, drop them on the field, and decide what the money goes into next — more DPS, or the wall that buys you the time to afford it.

WHAT YOU BUILD

Turrets — the core of the line, upgradeable per unit. Walls — reroute the swarm instead of tanking it. Tanks and starships — mobile units that plug holes the static line can't. Repair bays — keep the front from melting between waves. Workers — your economy: under-invest early and you stall by wave 20.

AND WHEN THE LINE BREAKS

Call in a nuclear strike. You aim it yourself — click the spot, watch it clear. It's on a cooldown, so spending it two waves too early is a real mistake.

AI AUTO-PLAY

Turn on AI mode and watch it play the stage for you, with a learning and hitmap overlay showing where it thinks the pressure is.

CONTROLS

Mouse, or touch on mobile in landscape. Click a turret in the bottom bar to buy it, then click a tile to place it. Click a placed unit to upgrade or sell. Click the nuke button, then click where you want it to land. M opens the menu, ESC closes panels.

OTHER THINGS

1x to 4x speed control. Plays on desktop and on phones in landscape. Five languages: English, Korean, Hindi, Japanese, Chinese. About 5 MB total, runs fine on low-end hardware.

Currently stage 1. I'd like to know two things: does the difficulty curve feel right, and is the economy too slow in the first minute?
