Corpus vs. Infested Easter Egg Demo
By logging in as username "corpus.outbreak", no password, the game will run a stress-test demonstration, in this case an endless gauntlet between the Corpus and the Infested factions, on a basic-textured arena. It's mostly useful for, as the name implies, testing how much a PC's processing and graphics can handle at once. If technical information (RAM usage, ping gauge etc.) was previously enabled, it'll also display during this demo. At worst, it's still a very interesting screen-saver.
