How to Play Moshi Monsters - Katsuma Unleashed
Quick start
Enter the first level, practise one short jump and defeat or pass the first obstacle. Read the ability prompt when a friend is rescued, then test that action on the matching route.
Controls
Move Katsuma with the DS directional controls and follow the displayed jump, dash and attack actions. Use an unlocked ability when its obstacle calls for it; check the landing space before combining movement with an attack or a long dash.
Moshi Monsters - Katsuma Unleashed — About this game
Katsuma faces Dr. Strangeglove’s robot Moshlings in a side-view platform adventure. Jump across hazards, dash through obstacles and rescue friends whose abilities help open further routes. The journey moves between themed worlds with enemies, hidden rewards and boss encounters rather than the pet-care routine of Moshling Zoo. Begin in the opening level, practise a short jump and inspect the first obstacle before committing to a long dash. When a new ability becomes available, read its cue and consider a route you could not previously reach. Use DS directional movement and the displayed jump, attack or ability actions; collect only after checking where you will land.
