A new Prey Dev Diary is up on the 3D Realms website. Chris Rhinehart, Prey Project Leader reveals the PC demo is ready and they are currently wrapping up the Xbox 360 demo with the aim to release next week.

Some of the level designers have been creating new DeathMatch levels for the game. They've been working on some new looks as well as creating some levels that are better designed for one-on-one battles (most of the levels in Prey are designed to work well with 4-8 people, although a some also function pretty well with fewer than four players). We don't have an ETA when these maps will be available. They've just started on them and aren't at the testing phase yet.
