ABOUT THE GAME

Pass through random terrain,
Proceed to the next loop.

``Nuklear Klone'' is a free PICO-8 browser action created by freds72. Suzie and Bob are trapped in a world where they battle enemies and pick up weapons as they navigate random maps and multiple biomes.

01

Navigate through random maps and multiple biomes

The official BBS post lists random maps and multiple biomes as game elements. Move through the terrain and fight multiple types of enemies as you progress.

02

Fix the direction of the gun or aim with the mouse

In keyboard operation, the arrow keys serve as movement and gun direction, and button 1 shoots and fixes the direction. If you switch to mouse operation on the start screen, you can move with the arrow keys, aim with the mouse, and shoot and obtain weapons with left and right clicks.

03

Pick up weapons one by one and challenge the loop

Multiple weapons are included, but you can only have one at a time. Change weapons by pressing button 2 or right-click, and see how far you can progress as the difficulty level increases according to the loop.
