Explore procedurally generated dungeons in Deadly Wonderland. Collect new weapons, shields, and companions as you venture deeper into the dungeon. Discover a wide variety of items and enemies, and even recruit defeated enemies as companions. Upgrade your equipment and recruit stronger companions to reach even deeper floors.
This app features three game modes:
• PSI Masquerade – PvP battles using randomly assigned PSI abilities
• Transrealm Masquerade – PvP battles with your own equipment and companions

• Play Solo
In Deadly Wonderland, AI companions will join you whenever no other players are available. A fully offline mode is also included.
In PvP, AI opponents can be added when there are not enough players. You can also practice against bots in Offline Battle Training, which follows the same rules as real PvP matches.
• Play Together
Deadly Wonderland supports up to 3-player co-op, while the PvP modes support battles with up to 6 players.
