Flinter is an optional Rat Bandit that is located past the room used for the "Splinter Group" mission. There is a series of five lights located on the wall above the Dahl chest, which turn from red to green by using switches located throughout that same room. The switches are the pipe valve, a ground lever, the television, and a wall lever. To make Flinter spawn, you must make all 5 lights turn green, which can be done by doing the following (in order):
- Pull wall lever once
- Use ground lever once
- Use television twice
When all the lights are green, Flinter will crawl out of the hole to the right of the chest. He has a shield and a ton of health (relative to his level). When killed, he has a chance to drop the RokSalt shotgun.
