What is Undercrown?
Undercrown is a top-down 3D dungeon brawler with a nasty little twist: getting to the treasure is only half the run.
Pick one of 8 heroes and cut your way down three floors - 18 rooms, each with its own colours - past the Gravewarden and the Maw Mother to the Underking himself. Every hero fights differently: the Vanguard swings a greatsword, the Paladin holds the line with sword and shield, Kachujin uses nothing but fists, the Ninja works twin daggers, Erika picks enemies off with a crossbow, Medea casts from a staff, the Captain brawls with a cutlass, and Heraklios brings a greataxe to every argument.
Then the twist. Beat the Underking, take his crown, and the whole mountain starts coming down - because that crown was the only thing holding it up. Now you have to run all the way back to the mine lift through collapsing rooms, falling rock, doors on timers and monsters flooding back in. You are not done until you are standing in daylight with the crown still on your head.
- 8 heroes, each unlocked with coins you bank between runs
- Level up mid-run and pick one of three upgrades - no two runs build the same
- Normal, Hard and Nightmare
- A full run is 6-8 minutes, if you survive it
How to play Undercrown
Get down, take the crown, get back out alive.
Desktop: WASD or the arrow keys to move, left-click or Space to attack, Shift to roll, P to pause, M for music.
Touch: left thumb stick to move, attack and roll buttons on the right.
Smash crates and barrels for coins and potions, watch for spike traps on a timer, and roll through anything you cannot out-trade. Kill enough to level up and pick an upgrade. Each new floor heals you and hands you a free one. When the Underking falls, run - the way out is the real fight.
