The plot is based off of Toy Story 4, and follows a similar timeline. There are several small differences, but the overall lot is the same.
You play as Buzz Lightyear, an old, washed up toy that hasn't been popular since the 1990's. It is very hard to hit something with, because of his constant drunken state, but he is very powerful. He also can shoot a lazer, which causes an enemy's eyes to melt and brain to explode.
This is considered by many to be the baddest shame that was associated with Disney to be produced. Despite this, the Salem s considered to be fairly awful, even Buzz hated it.
