Digger 21: Dig, Shoot, Survive

Digger 21 is a fresh take on the classic tunnel-digging arcade. Steer your drill rig through dirt, collect every crystal on the level, drop gold bags on monsters and shoot your way out when they corner you.

TEN PLANETS, TEN TWISTS
Every planet adds its own trap: hard rock and boulders on Earth and Mars, sandstorms and spike traps, wind gusts and wormholes on Jupiter, conveyor belts on Saturn, ice and freezing casts on Uranus, darkness on Neptune, slow zones and mimics on Pluto, and lava with everything at once in the Kuiper Belt. 85 levels and a boss at the end of every planet.

MONSTERS WITH CHARACTER
Nobbins chase through your tunnels, Hobbins dig their own, Ghosts phase through dirt, Bombers explode, Spitters shoot acid down straight corridors, Moles chew through rock. Bosses use the planet's own mechanic against you.

UPGRADE YOUR RIG
Earn coins on every level and spend them on 14 upgrades: bigger ammo belt, extra lives, shield, drill speed, treads, magnet, radar, headlights and more. Later planets hurt until you gear up.

DRESS IT UP
Nine drill rigs from a rusty classic to a hovering saucer and a living shadow, seven weapon styles with their own effects and sounds, five monster skin packs. Cosmetics are bought with crystals that you also earn by playing.

MADE FOR PHONES
Virtual stick and a big FIRE button, short levels, three stars per level, daily missions, login streaks and a minimap on the big boards. Works offline.

Digger 21 is free to play. It shows optional rewarded ads and, from the second planet, occasional ads between levels; a single purchase removes them for good.
