About MR 333 II: Planetbirth

After leaving the portal you are taken HOME. Home of origin will require you to seal off entities linked from escape portal. It will not take long for them to follow back, and thus opening the doorway for MR 333. Failure to complete the ritual you embarked on will open your home to the being and his entities wish to ensure this happens. The only way to seal off and continue the ritual is to birth a prison planet in their realm, a place where the vibrations can hold them and not give them reign in yours. Become pregnant, birth a planet and seal off the entities.

MR 333 II: Planetbirth features a first person perspective with frantic gameplay requiring you to locate items, fight entities and run from enemies existing in your realm.

Navigate the house after returning "Home" and explore the surrounding areas. Rebuke entities and run from those corrupted. Become pregnant with the planetary fertile snake and fight the entities through each trimester.

This is a small sequel to MR 333 that features an additional level to take place directly after the completion of the ritual from the previous game.

"MR 333 II: Planetbirth" is a somewhat weird first person adventure survival/suspense game with a bizarre red monochrome graphics thing going on that make what might be a reasonable looking game look horrible. The gameplay is lacklustre and this feels a lot more like a tech demo or a homework assignment than a real game. The graphics in this game are passable, but could be better. And while it's vital for any game to have impressive visuals (gaming is a visual medium, after all), there's more to a game than just the graphics. To be worth a gamers time, the game must match top tier visuals with top tier gameplay, and that's not happening here. Not every "free" game really is. There's often MTX, or content locked behind DLC, or donations being requested, or any other number of things that could mislead gamers, but in this case I'm glad to say this really does appear to be a fully free game. Nothing demonstrates a developers belief in themselves and their work than giving it away without any remuneration. This is a service to themselves, and the gaming industry, and should be applauded.
