What each player can do here

P1 · Sackboy 1
  • Run, jump, flutter in mid-air and roll; rolling is quicker than running.
P2 · Sackboy 2
  • Same moves as Sackboy 1, and up to four Sackboys can play together. You can grab, slap and roll into each other, and teamwork levels have you throw a partner up to high ledges.

If your skill levels differ: Every Sackboy has the same moves, so the split is by job inside the teamwork levels: one of you throws, holds a scale or carries the squid while the other climbs or crosses. In Swipe Right one player stays on the ground to help the one on the wall; our suggestion is to give that job to the newer player. How to split the roles

The main path

Part 1 of 5. Clear the station and reach 130 Dreamer Orbs.

  1. BothMain levels: Boot Up Sequence, Touch And Go, Fight And Flight, Science Friction, Pros And Conveyors, One Track Mind, This Way Up and Escape Velocity, then the boss level Nervous System.
  2. BothThe boss level needs 130 Dreamer Orbs.
