Swampmaster™

A completely original retro NES adventure game

Several years into development, we're making outstanding progress and implementing some really cool features.

What can you do in Swampmaster? Explore the mysteries of the swamp, battle denizens of the deep, spelunk through cavernous mountains, retrieve forgotten relics with magical powers, and save the world from annihilation, all on either a computer ROM or an actual Nintendo Entertainment System (NES) cartridge!

More photos, videos, and gameplay demos coming soon.
