📋 About This Mod

A mysterious cargo ship crashed onto Planet 4546B five years ago. On board were various species of fauna, bio-engineered by a shady company that is not formally recognized by Alterra. Most were destroyed in the explosion, but a few specimens managed to escape the wreckage. These terrors are only known under their code names BLOOP and BLAZA.

THE BLOOP:

The Bloop is a large, mysterious, awkwardly-sized mass of flesh and teeth. Some living Bloops reside in the Mushroom Forest and other shallow areas, but many specimens are entirely unaccounted for, blending into the depths.

BLAZA LEVIATHAN:

This snake-like leviathan inhabits various cave systems on the planet. This creature is over a hundred meters in length and has an incredibly powerful bite. Don't ever let your guard down.

Customization

This mod has customization for the following, all found in the in-game options menu:

  • []Enable blaza spawns[/]

    []Enable early game bloop spawns (right outside spawn, at the grassy plateaus)

    STOP SPREADING MISINFORMATION - This setting is always DISABLED by default, and this has been the case for years. Stop harassing me about that "decision" when streamers/users are the ones enabling the option themselves.[/]

    []Enable deep water bloop spawns[/]

Make sure you set these settings BEFORE you explore your save file, and make sure to restart the game after changing the config.
