Delta Zero

Delta Zero is a side-scrolling action game with non-linear, metroidvania-style level design. You choose one of two playable characters and explore a connected world, taking on areas in any order. Local co-op is available, and a second player can join at any time.

Explore and fight

A central hub connects to the game’s areas. You dash, duck and wall-jump through them, fighting enemies unique to each area. Special weapons are unique to each character, while permanent power-ups are hidden throughout the world. Some obstacles can only be destroyed with specific weapons, revealing hidden paths and secret items.

Defeating bosses grants you a new weapon and increases your maximum weapon energy. The order in which you tackle areas and bosses affects how difficult they are: as you defeat bosses, enemies grow stronger, with increased health and damage as well as smarter behavior. Stage hazards also become faster, tougher and more damaging, and their behavior changes. Bosses power up in a similar way, so the game’s difficulty does not simply decrease as you progress.

Modes and progression

The game has three difficulty modes, with auto-saving checkpoints and infinite lives in each. Its changing enemy and hazard difficulty makes the order of your progress shape each run and supports replayability.
