It works perfectly fine on the Meta Quest 2. Just need to pick up the ship and then you automatically start flying and hopefully you have strong VR legs like me otherwise you might get nauseous. It's okay for being free. It's really just a shoot 'em up and you even have some upgrades. Xortex is much better though and also free. Rate 5/10.

Operation Pill is an Early Access free VR game. It worked on my HTC Vive and Index and Meta Quest 3 system, looked ok, played ok, sounded ok. You have viruses to shoot while swimming through blood vessel. Very short game play, i played two rounds in 12 minutes. You can increase the difficulty. Controller grabs the sub to steer and trigger to fire guns. Maybe try this game.

💬►' very short, repetitive, lacking fun ' 🔥►Meet people TESTING now (in group CHAT link below) 🏆►VR Giveaways and CHAT 🏆 https://steamcommunity.com/groups/JoinUsInVR" [b]Dear DEV;[/b] If you are still working on this game, please DM me or and comment on my review. I would LOVE to have ALL our group's VR game-testers play this as-is and give you ideas to boost the fun. I have some too. If you update it and I play it and I see is more fun, I would LOVE to update my review to reflect that. PCVR needs dev's who don't give up!!!! Best of luck to you either way.

If you enjoyed playing apps like "Conscious Existence – A Journey Within" or "InCell VR" you will enjoy the Innerspace game of 'Operation Pill'. It's a pretty simple shooter'em up in which you have to kill the viruses flowing through someone's bloodstream and I suppose save their life. It's as if Covid never went away! But in all seriousness, this game's simplicity is what makes it so fun to play. You can move freely about in the bloodstream with your scuba-driver and you can even pick up a few power-ups along the way giving you a total of 4 guns! It's not something you will play over and over, but it is 100% free, easy to play and has a high score to challenge yourself with. You just can't go wrong here! You can check out my gameplay video here - https://youtu.be/xHRIX2YMSaY But seeing as it is free it is probably best you check it out for yourself!

Operation Pill is a compact virtual reality action game that takes an ordinary medical idea and transforms it into an arcade-style microscopic adventure. Developed and published by xr407, the game places the player in control of a tiny medicinal capsule traveling through the human body. Rather than treating its subject as a realistic medical simulation, it uses the bloodstream as a creative setting for shooting, flying, collecting equipment, and surviving encounters with harmful microorganisms. The result is a curious VR experience whose unusual premise is easily its strongest characteristic. The central objective is to protect the organism from pathogenic bacteria while navigating through a blood vessel. The player pilots the pill through this confined biological environment and uses a germicidal cannon to eliminate hostile targets. Movement and combat are designed around VR, making the experience more immersive than the same concept would likely feel on a conventional display. Traveling through an oversized representation of the bloodstream helps create the sensation that the player has been reduced to microscopic proportions and sent on a mission inside a living body. Combat i…

Games like Undertale that remember what you did

Undertale's own listing calls it the RPG where you don't have to destroy anyone. Games like Undertale that keep that idea: permanent choices, fights you can talk past, worlds that notice.

Most games like Slay the Spire copy the cards and lose the map. These keep the risky-or-safe choice, from a three-floor train to a deck made of poker hands.

Planet Coaster DLC: skip the collection, buy the packs

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.
