The Steam bundle for Eropsychosis: The Project Elysiara and Sex Formula is now live. If both games are on your wishlist, you now have another way to pick them up.

Eropsychosis: The Project Elysiara

Built in Unreal Engine 5. You play David, an engineer who has lost his memory. He wakes up on a starship with only one companion: Lucy, an android who has gone haywire.

Lucy controls the ship's oxygen, gravity and cabin temperature. You have to deal with her while exploring each section of the ship and recovering the scattered Peak Intimacy Records.

Sex Formula

You meet Reika and move in together. But even after you've become intimate, she won't agree to officially date you until you've truly satisfied her.

Reika has her own menstrual cycle, and her sex drive changes with how she feels each day. The game supports VR, and you can also play directly on PC without a VR headset.

With the two games side by side, we'd like to take this chance to introduce each story.

Chief engineer David wakes up on a starship with no memory. The ship's AI android, Lucy, has malfunctioned. She controls the oxygen, gravity and cabin temperature, and demands that he search each area for the scattered Peak Intimacy Records.

Under Lucy's control, David has to explore the ship and piece his memories back together.

Sex, Secrets & Used Tech

You run a used electronics repair shop in Suka City. One day Ivy, a silver-haired thief, walks in with a stolen phone and drags you in as her accomplice.

From pulling jobs together to stumbling onto a deal between top police officials, things keep getting more tangled, until the trail leads all the way to the mayor.

The bundle is now available
