School Grounds Survival

Detention was yesterday. Today is the apocalypse.

Overnight, students and teachers have turned into mutants, and the school won't let anyone out. Principal Dr. Zorn has only one announcement for you: "Mr. Scrubbs, the hallways still haven't been mopped!"

You are the janitor. Your weapons are whatever is lying around the school: a mop, a stapler, a compass, a Bunsen burner, a dodgeball. They fire on their own – you decide where to stand, where to dodge and what to buy at the snack kiosk.

Build your build

• 69 weapons from everyday school life, each upgradeable to level 3
• 20 evolutions: two matching weapons fuse into a new one – water pistol and Bunsen burner become the Steam Cannon
• Subject sets: collect weapons and items of the same subject for bonuses in Chemistry, PE, Maths, Music, Art, Physics and Janitor
• Reactions: wet plus electricity makes a short circuit, wet plus fire a steam explosion
• Risky items: big advantages with a catch

A new subject every lesson

Mid-wave the bell rings and the rules change for everyone: in Physics projectiles bounce more, in PE everything is faster, in Chemistry acid puddles appear. On top of that come school events like power cuts, fire drills and vocabulary tests.

9 chapters, 9 bosses

From the ground floor through the cafeteria and the gym all the way to the school bus: every chapter has its own room with its own rule and ends with a boss – from PE teacher Ms. Eisenhart to the Thing from Stall 3. Every boss has a signature attack and fills the room with bullet hell.

Ten characters, each plays differently

The cafeteria cook with huge area attacks, the tech nerd with turrets, the student council president whose sets kick in sooner, the principal's son who throws money around – and a secret character who only shows up after graduation. Plus three companions: the school hamster, the school dog and the lab toad.

• Endless Detention with a worldwide Steam leaderboard
