What the developers have to say:

Why Early Access?

“We do believe that if we want to develop the best game possible, we have to work with our players. Our goal is to develop a realistic military FPS for Virtual Reality headsets that every player loves and enjoys. Without player feedback, we couldn’t accomplish that. Moreover, when the full version of the game will be accessible, we would like it to be free of any defect or bug.
That is why we need players’ feedback, even during development. We take every feedback, opinion, critical thought seriously, so please don’t hesitate to contact us. We’re listening, and as an addition, you will become part of the development process!”

Approximately how long will this game be in Early Access?

“We’ll release the full version when every aspect of the game is polished, and we’re fully satisfied with its state. :) Currently the estimated release date is early 2019.”

How is the full version planned to differ from the Early Access version?

The full version will also contain:
- The 2nd half of our story
- A lot more weapons and attachments
- Shorter, challenging Co-Op missions

What is the current state of the Early Access version?

The game's core mechanics are layed down: physics based interaction, customizable weapons with various attachments.
The EA version will contain the tutorial, first half of the story and a Co-op missions.

Will the game be priced differently during and after Early Access?

Price may increase moderately when we release.

How are you planning on involving the Community in your development process?

"We regularly monitor our community channels, including our forum on Steam, our Discord and our social media (Facebook and Twitter). We extensively test the game/its updates before it goes live, but if players find a bug, they can report it and we’ll fix it as soon as physically possible.
We also take the best/most upvoted ideas and add them into the game.

Our quest is to develop the best, most immersive military tactical shooter available for VR!"

Zero Caliber VR: public demo, EA release, dates

Hey guys and gals!

In the past few months, you could've read different release dates and confusing deadlines surrounding Zero Caliber VR.

Let's make a clean breast about it all!

Public demo: to be released on 25th October, 2018 <available for free until the release>
EA release: dropping on 9th November, 2018
Wishlist Zero Caliber VR to get notified about announcements and important news!

"But Devs, why all the delays?"

Good question, glad you've asked. :)

During the Closed Alpha test we've realized that there are many Oculus Rift and Windows Mixed Reality players eagerly waiting for Zero Caliber VR.
Their numbers far exceeded our first estimations!
That is why we've decided to develop the control support for all these VR systems before releasing any public version of the game. No one should be left out!
Another reason for the delay is all the feedback our wonderful Alpha Testers sent our way. We've been busy fine-tuning the game and eliminating bugs based on our community's feedback. We can't thank them enough!

We've also decided to update the game's engine to the latest version before going public. Such an update takes extra time as we have to make sure our game runs flawlessly on the new version as well.

As we're still a small Indie Studio with limited resources, we ask for a little more patience. Don't worry, you don't have to wait for too long! We're only 1 month away from the public demo, then 2 weeks later comes the release. It's all for a better experience for you guys, we promise! :)

About This Game


Zero Caliber VR is a first-person tactical shooter developed by XREAL Games exclusively for premium Virtual Reality headsets.
The story brings the player to a dystopian United States in the not too distant future where physics-based interaction combined with hyper realistic weapon handling and stunning graphics will make you feel like you’re physically part of the action. Fight either alone, or with your friends throughout the whole campaign, which is fully playable in Co-Op.
Action-oriented story, gripping gunfights, realistic weapons with an on-the-fly swappable attachment system. Immersion like you’ve never felt before in a VR military shooter!


Handle, aim and reload your weapons with real-life movements! We modeled the in-game weapons based on their real-life counterparts paying extreme attention to detail. Each weapon has its unique reloading method that you have to learn and practice to fully master them.
If you fancy explosions, just grab a grenade and throw it at the enemy. After you pulled the pin of course.
Stay in the open for too long and you’re dead. Try to find cover instead, duck, crouch, sneak, peek around a corner, clear obstacles with real-life movements. Military combat isn’t all about shooting. Being aware of your surroundings, the terrain, and working together with your squadmates are all part of a successful mission. Don’t let your fellow soldiers down!


Everyone has a unique playstyle. Is accuracy your thing? Put a laser sight on your assault rifle and take accurate shots in semi-automatic mode, or just grab a sniper rifle. Are you more of a shoot first, ask later type of person? Take a shotgun, or dual wield your machine guns in fully automatic firing mode. Be careful though, recoil can make your job really difficult! Combine your favourite gun with your favourite attachments on-the-fly to find out which variation suits you the most!


Water is life. Someone should’ve made that clear before humanity started poisoning Earth with microplastics. Now water is death. People are fighting for drinkable water, for survival.
The military tried their best to keep order, but inevitably they got overwhelmed. That’s when mercenaries appeared.. then entire private armies.. and then when hope started to fade away came the religious cults. The most fearsome of all is a secretive organization worshipping Tlaloc, the aztec God of rain. The “Tlalokii”, as they call themselves. Their motto? “Join us or perish”. What is even worse, they know something that can change the fate of humanity.
Be part of this action-packed, story-driven VR adventure where you fight alongside your fellow soldiers trying to keep order… or what’s left of it anyway.


We place realism above anything else. Graphics and ambiance are crucial parts of this, that’s why we took extreme care in audio and visual design. Explorable open environment, stunning graphics, background noises, realistic weapon sound effects.

A constantly developing military VR FPS experience that will surely make you forget that you are in a video game!
