Mine diamond

About Mine diamond

Mine diamond drops two heroes into a relentless defense mission: keep the Big Diamond intact while waves of enemies close in from every direction. The game runs on both computers and mobile devices, and supports solo play or a cooperative two-player session where each person commands one of the two characters.

The two heroes are Obby and Noob. Obby covers the left side of the screen and Noob covers the right, so a second player can jump in without any extra setup. In single-player mode, one person manages both characters independently. Heroes attack nearby enemies automatically, which keeps the action focused on positioning and defense rather than manual targeting.

Enemies that slip past the heroes and move off-screen chip away at the Big Diamond's durability. A special enemy type called Creepers poses a permanent threat — they deal their damage regardless of whether they are destroyed before reaching the diamond. Defeated enemies drop diamonds that are automatically drawn toward the Big Diamond, and collecting those gems funds new weapons and upgrades.
