Project Introduction

Play Leif's Adventure, a story-driven co-operative 2d action-adventure about friendship and teamwork. A boy never meant to be a hero, learns that pure strength is not always the answer! Guide two completely different characters through the adventure of their lifetime. Combine the unique abilities of both characters to overcome the evil sources of the Netherworld.

Play Leif's Adventure with a friend in co-op mode or play alone in single-player mode. Swap between the modes at will and customize the way you play.

Play with two characters simultaneously. Swap between characters and utilize different abilities and skills. Leif for fighting, jumping, running. Ghost for exploring areas, activating ghost objects, platforms, collectibles, and stun enemies.

Progression skill-based gameplay. Leif can learn various skills including powerbomb, air attack, and throwing weapons as well as upgrade combat weapons such as his signature hammer and his maximum health.

Equip Leif with a huge selection of weapons. Whether it's a short sword, hammer, axe, or spear, the range is huge. But you can also collect all the weapons dropped by enemies and use them against them. Pay attention to the elemental abilities of the weapons and armor. Fire, ice, and electricity have different advantages and disadvantages.

Navigate a hugely diverse world filled with adventure and explore six different levels. Battle against huge secret monsters and a variety of creatures, golems, and other deadly adversaries. Combine Ghost’s supernatural talents and Leif’s ability to jump, run, slide, crouch, and climb up ropes to explore the deepest reaches of each level.
