Prometheus Rising v017 Released
In this version, players are protected from getting killed by (sometimes invisible) monsters for the first 10 seconds of the game in the vicinity of world spawn. Also re-balanced monster and creature spawning to make things more consistent. Sounds were added to the Aethon (flying alien).

Thanks! I really had a problem with getting killed by invisible monsters the first 10 seconds of the game!
glad that helped. i have a new release coming out within the next few hours hopefully that will keep more monsters around on the surface than currently as well as adding small dungeons within cave systems and Octohugger spawns that create Beluga-bursters and Belugamorphs.
