Don't Panic, Defend!

Free browser demo of Don't Panic, Defend! — the full game is coming to Steam.

Enemies keep coming. Your soldiers fight on their own. You decide who to buy, when to spend, and what the army is made of.

• Build an army, watch it fight. You don't control units directly — you recruit, and they hold the line wave after wave.
• Every copy of a unit costs more than the last, so you're always weighing more of the same against something new.
• Losing only costs the gold you're carrying. XP carries over into a star map of permanent upgrades, so the next run starts stronger.
• This demo has 2 chapters, 40 waves and 2 bosses, plus endless mode — in 11 languages.
