Eternal Survivor is an action-packed game developed by OLKA for Windows. The game sets you in a dungeon room full of zombies, and your objective is to survive using four different firearms. The game is designed with a top-down/isometric view, and you move with the WASD keys while aiming with your mouse.

The game's shooting is automatic, and as you level up, you have three different options to choose from. You can upgrade your weapons, stats, or unlock new skills. The game runs for about 15 minutes, and there are difficult modifiers to make the run easier or harder.

Eternal Survivor comes with different upgrades for weapons or stats, which makes the game more exciting and challenging. The game's graphics are impressive, and the sound effects are realistic, which adds to the overall immersive experience of the game.
