Description (written by the developer; not a statement by this register)
How to play: Stick together - certain levels/area have monsters that will target solo players Stay in light areas - some areas have lots of lighting and others dont, the areas with more lights are safer as Umbrals are photophobic and weakened in light. Always have a firearm on you - Guns would not deal critical damage to the Umbrals, but could stun them for a short period of time. Don't linger for too long - Staying in the same room for too long may result in more Umbrals spawning outside or inside the area. (Anti-Afk) Only exploit in private servers - It's better to not exploit at all, but if you MUST, please do so in a private server, otherwise once our anti-cheat detects you, the map will get entirely deleted. There are multiple gamemodes planned to be added: "Infiltration", "Rescue", "Tutorial", "Story", "Survivors VS Umbrals", "Flashback", and "Umbral Waves" Sometimes Azyx (Owner/Developer) is inside the lobby, feel free to ask anything. More info inside the game.
