About Coridden
Coridden is an old‑school hack‑and‑slash action RPG that lets players shift between a human avatar and fully realized monster forms, each with its own skill trees and abilities. The shapeshifting system is central to both combat and traversal across the hostile planet Heera.
The game supports solo play and drop‑in/drop‑out co‑op for up to four players, both locally via split‑screen and online. Players assume the role of one of four siblings, exploring open areas, uncovering side quests, and seeking the secrets of a legendary city.
01 / THE GUIDE
Shapeshifting Mechanics
Players can switch freely between human and beast forms, using each form’s strengths for combat, navigation, and obstacle overcoming. The beast forms also act as faster traversal tools, allowing players to cross terrain that would block a human.
Both forms develop through gear, attributes, and dedicated skill trees. Humans choose from four classes, while beasts draw from seven masteries, giving players the ability to customize progression in each identity.
- Try each beast to see which traversal style fits your map routes.
- Balance gear upgrades between human and beast to keep both forms effective.

Combat System
Combat is action‑focused, requiring timed attacks, dodges, jumps, shapeshifts, and abilities against aggressive beasts, bandits, and machines. Gear and skill choices directly influence combat effectiveness.
Success depends on recognizing when to shift forms and when to employ abilities, as each enemy type presents distinct challenges that can be mitigated by the appropriate form.
- Observe enemy patterns before committing to a form change.
- Mix melee and ranged gear to cover varied threats.

Co‑op Features
Up to four players can join in drop‑in/drop‑out co‑op, either offline/locally or online. The mode adds a team mechanic where players can ride on each other’s backs, forming a cavalry unit.
In co-op, teammates can also ride on each other’s backs to become a strong cavalry unit together.
- Coordinate back‑riding to handle stronger enemy groups.
- Use split‑screen for clear communication when playing locally.

Exploration yields new gear and DNA strands while journeying across the hostile planet.
