Like many of my previous doors, these doors open when shot. Unlike my previous doors, these are (obviously) designed for Forerunner maps, and each come in multiple color varieties depending on what kind of Forerunner map you're making.

In order of appearance:

- Builder Door (Blue, Orange, and Purple): based on the doors in Halo CE, these are quite small and feature two halves that slide into the walls, and one part that retracts into the floor.


- Promethean Door (Blue, Orange): these are based on the doors in Halo 4; they're much larger, and each half simply slides into the wall. However, it should be noted that if you're going to use these, make sure to weld the scripted bits of each half together first, making two groups.


- Lifeworker Door (Blue, Green): this one's an original design, and dilates like the various Metroid doors I've made before.
