CONTAINMENT GRID Wishlist on Steam

Draw the maze. Graham builds it.

A tower defense game for PC. You plan every wall and pick the towers. Your dog carries each order onto the floor and builds it, live, while anomalies pour through the gates.

How it plays

One shift, three jobs

Every operation runs the same way: you plan, Graham builds, and the gates open on a timer whether you are ready or not.

1Draw the maze

There are no fixed lanes. Walls are cheap, and every one changes the route the anomalies take to your core, so the map is yours to shape.

2Pick the towers

Twelve tower families with three specializations each. Frost slows, Mortars splash, Railguns pierce, and Flak handles the flyers that skip your maze.

3Send Graham out

Nothing appears by magic. Graham walks to each spot and builds it, even mid-wave, so where Graham is standing when the boss arrives matters.

The crew

Graham is on shift. Nori is the backup.

Your companion is a real character on the board, not a cursor. Bring them home to the Den between operations to learn tricks, take on a job and change outfits.

Your companion

Graham

The founding dog. Warm tan coat, floppy brown ears, and a little faster at building than the rest of the crew.

Backup

Nori

The founding cat. Tuxedo coat, sage green eyes, and a little quicker across the floor than Graham.

Story

It started with one crate

This is the comic that opens the campaign: eleven operations, from the Workshop Yard down to the Core Vault.
