Essentially the game is similar to games like GTA and Minecraft were the player is free to explore, but it will be more of a semi-open world instead of being a sandbox.
The premise is that Craftworld is invaded by alien squirrel creatures named "Squaliens" that were once friendly squirrels gone-bad due to sackpeople bullying them...
Sackboy must save his world from those furry foes leaded by Squirrelina. Sackboy must save the baby Oddsocks, his girlfriend Honey, rival-turned-ally Dark Sackboy, and Luna (Dark Sackboy's girlfriend)
