Attack Hole puts a black hole at the center of the action, challenging a single player to consume as many weapons as possible before the timer runs out. Once the collection phase ends, the fight begins — every weapon swallowed becomes firepower aimed at a giant enemy that must be destroyed. One scene shows a large red humanoid figure standing on a white and blue checkered floor directly above a black hole. Another moment reveals objects arranged in a pattern resembling a human skull with large circular eye cavities. A separate scene shows seven red treasure chests with gold trim lined up behind multiple red sacks filled with gold coins.
The goal is straightforward: swallow all the weapons scattered across the stage before the timer expires. Once time is up, the weapons collected are turned against a giant enemy in a final battle. Destroying that enemy is the ultimate objective, and the arsenal gathered during the collection phase determines what firepower is available for the fight.
Fans of black-hole mechanics will find plenty to enjoy in Mine: Black Hole, where consuming objects across six increasingly large levels drives both size upgrades and a diamond-based skin system. For the weapon-collecting and upgrading side of Attack Hole, GunMerge.io delivers fast-paced merging of guns to build ever-stronger firepower against escalating challenges.
