Weekly World Boss ranking is live! Beat more bosses, faster, for Gems, a gold border and medals. From a rusty pistol to legendary guns, on to the Demon King!
Auto-battle and grow your own arsenal!
Grow Gun is a side-scrolling pixel idle RPG.
• From a rusty pistol to legendary weapons! Start as a rookie gunslinger, grow your gun and take on tougher bosses in every new region.
• Collect weapons: summon 9 weapon families: guns, lasers, water guns, slingshots, crossbows, bows, cannons, railguns and shotguns.
• Merge gear: fuse 3 pieces of the same slot and grade into the next grade, all the way to the top and beyond.
• Combine skills: learn all 28 skills as you level up, then pick your favorites for the 5 skill slots that open with your level.
• Boss fights: 14 lands from the meadow to the Pirate Harbor, Clockwork Fortress, Sky Castle, out into Outer Space with its aliens and at last the Demon Castle, with hordes and 28 bosses. The final boss: the Demon King!
• Pets and relics: power up your stats with pet companions and relics.
• Lap challenge: clear all 14 lands to start Lap 2! Enemies grow stronger each lap, and their frame color shows which lap you're on.
• Limited-time events: level up faster with Gold and EXP boost events.
• Cloud save: link your Apple or Google account to continue on any device.
This is an online game that requires an internet connection.
Includes optional rewarded ads.
