About Polydangerous Demo

Three missions. Three biomes. One hostile planet. Play the opening campaign of Polydangerous and find out why every contractor owes the company more than they'll ever earn.

Build bases, arm yourself with 10 weapons, evolve your structures, and fight through 15 waves across frozen outposts, volcanic furnaces, and hostile rock formations. The demo includes global leaderboards and enough depth to experiment with different strategies.

MISSION 1: LANDING SURVEY

Your first deployment. Rocky terrain, basic threats. Learn to build, learn to shoot, learn to not die immediately. 5 waves of escalating pressure.

MISSION 2: FROZEN OUTPOST

Ice spires, glacial ridges, and geyser vents. New enemies, new weapons from supply drops, and the realization that your walls aren't thick enough. 5 waves.

MISSION 3: THE FURNACE

Slag pools, forge pillars, and heat shrines. The full enemy roster arrives - including Ferrox mercenaries. Survive 5 waves and face what's waiting at the end.

10 WEAPONS

Rifles, shotguns, snipers, plasma rifles, cryo guns, miniguns, grenade launchers, rocket launchers, and an energy blade. Supply drops deliver new weapons each mission.

2 PLAYABLE SHELLS

Marcus (Soldier) and Elena (Engineer). One fights. One builds. Both die.

4 SKILL TREES

Combat. Defense. Architect. Economy. Enough depth to theory-craft across multiple runs.

13 BUILDINGS WITH EVOLUTION

Walls, turrets, tesla coils, mortars, cryo sprayers, decoys, mining droids, and more. Buildings unlock progressively and evolve through branching upgrade paths.

NANOPRINTS

Common and Uncommon collectible relics that modify your weapons and abilities. Stack synergies and discover combinations.

GLOBAL LEADERBOARDS

See how your performance stacks up against other demo players globally.

THEN WHAT?

Beat all 3 missions and unlock Helldangerous Protocol - endless mode where everything scales and nothing is safe. The full game continues with 24 shifts, 16 characters, 23 weapons, 7 skill trees, 144 nanoprints, and much much much more.
