ENDLESS™ Dungeon is a Rogue-lite Tactical Action game, set in the award-winning ENDLESS™ Universe. Recruit a team of shipwrecked heroes, plunge into a long-abandoned space station, and protect your crystal against never-ending waves of monsters… or die trying, get reloaded, and try again.
Dungeon of the Endless is a strange turn based, real time, tower defense, strategy, dungeon crawler. You control a party of units.
Endless Dungeon is essentially the same, but it's a twin stick shooter where you control one unit.
Is this a sequel to Dungeon of the Endless?
Story wise? I have no idea.
