About Rusted Moss
Rusted Moss is a physics‑based Metroidvania that blends twin‑stick shooting with a 360° aiming grapple. Players swing, climb, and fire at enemies across a melancholic, pixel‑art wasteland, using momentum to navigate and combat. The game also includes a Steam‑Workshop level editor, allowing creators to build and share custom stages. Multiple weapons, bosses, and endings give players reasons to experiment with both traversal and gunplay.
01 / THE GUIDE
Physics‑Based Grapple
The grapple functions as an elastic hook that latches onto moss‑covered structures, using kinetic momentum to propel the character. Mastering its timing creates fluid movement through rugged terrain. The system offers a full 360° aiming range, letting players swing in any direction rather than limited eight‑way movement.
- Practice catching momentum on small ledges before attempting long swings.
- Combine a quick grapple with a shot to keep enemies at bay while repositioning.

Twin‑Stick Shooting
Rusted Moss emphasizes tight, precise gunplay with a twin‑stick control scheme. Players can quickly switch among eight distinct weapons, from close‑range shotguns to long‑range snipers, to adapt to each encounter. The 360° aim works for both grappling and shooting, ensuring seamless combat flow.
- Swap to a shotgun for close enemies, then grapple away to reset distance.
- Use the sniper after grappling to finish off distant targets safely.

Boss Encounters
Six challenging bosses, ranging from powerful witches to machine monstrosities, each introduce unique mechanics. Players must dodge swords, avoid energy fields, and counter conjured spiders while managing grapple positioning and weapon choice. Success relies on blending traversal skill with accurate shooting.
- Observe each boss’s attack pattern before committing to a grapple swing.
- Switch weapons mid‑fight to exploit weaknesses revealed by the boss’s moves.

Steam Workshop Level Editor
The built‑in level editor lets players design custom stages using tiles, terrain, and gimmicks, then share them via Steam Workshop. Community‑made levels expand replayability and let creators experiment with new grapple and combat scenarios.
- Start with simple platform layouts before adding complex grapple points.
- Test your level with both weapons to ensure balanced difficulty.
05 / THE GUIDE
Narrative and Multiple Endings
Set in a desolate world where humanity, fae, and witches clash, the story follows Fern, a changeling, and the shadow Puck. Player choices influence whether the tale leans toward human or fae outcomes, leading to multiple endings. Dialogue with humans and fae reveals lore and hidden secrets.
- Talk to both human and fae characters to uncover hints about ending conditions.
- Pay attention to story cues during boss fights for clues on alignment.
