Playing Mixed Reality With Pets and Housemates Safely
Dogs, cats, kids and flatmates can wander into your swing. Safety tips for playing Sozo Tower Defense in mixed reality at home without any accidents.

Mixed reality is wonderful until the cat sprints through your play area. Because Sozo Tower Defense asks you to reach, aim and punch, and because the monster path runs across your real floor, it pays to plan around the living beings in your home. The terms of service say it directly: you are responsible for your own safety and for that of people and pets around you.
Why mixed reality needs extra care
In mixed reality you can see your room through passthrough, which feels safer, but your attention is on virtual monsters. A pet crossing the floor might look like part of the show, and you might not react in time. In VR mode you do not see the room at all, so you cannot see anyone walk in.
Before you start
- Tell everyone in the home that you are about to play.
- Close the door to the room if you can.
- Put the pet in another room with a treat or toy.
- Check the floor for toys, shoes and cables.
- Ensure your boundary or Space Setup is current.
Dogs and cats
Pets love moving objects, including your hands. Some may even chase your controller lanyard. If your pet cannot be shut out, play at a time when they are sleepy, after a walk or meal, and keep sessions short. If an animal enters the area, pause or stop. Hurting a pet or yourself is never worth finishing a wave.
Small children
Little ones are drawn to the headset and may run in unpredictably. Play when they are napping, at school or supervised by another adult. Never let children use the headset without checking the platform's age requirements. The Sozo privacy policy says the game is not directed at children under 13.
Flatmates and partners
Agree on signals. A sign on the door saying VR in progress is surprisingly effective. Share your schedule so nobody walks in unexpectedly. If your play area is in a shared room, arrange time slots.
Spectators are fine, if placed well
Having friends watch can be fun. Seat them well outside your reach zone and give them a clear view of a screen if you cast. Remind them not to step forward to point at things.
Fragile objects
Clear glassware, vases and electronics from the area, as the terms advise. Close windows or doors that might be bumped.
What to do if something happens
If you hit something or someone, stop, take off the headset, and check for injury. Do not continue until the area is safe again. In case of pain, seek medical advice as needed.
Use your boundary features
The terms ask you to complete your headset's room setup and keep its boundary features enabled. These systems exist to warn you before you walk into obstacles.

A sign on the door
A hand-written note reading 'VR in progress' on the door is one of the cheapest safety tools you can own. Add a time so people know when it ends. For households with kids, a visual signal such as a coloured card works better than words. Combined with a verbal heads-up, it dramatically lowers the chance of surprise visitors in your play area.
Planning the room like a stage
Think of your play area as a small stage. Before you start, decide who or what is allowed on it: pets in another room, children told to watch from the doorway, flatmates warned about the time. Then set the stage physically by moving low objects such as bowls, toys and shoes out of the way. In mixed reality it is easy to forget that the monsters are virtual while the dog's water bowl is real. A thirty-second walk around the space with the lights on prevents most accidents. Once the stage is clear, you can enjoy the game without half your attention on the floor.
FAQ
Is it safe to play Sozo Tower Defense with a dog in the room?
Only if the dog stays out of your reach zone. Ideally put pets in another room.
Can other people see what I am doing?
If your platform supports casting, they might. Sozo itself has no online features described.
Should I use mixed reality or VR with housemates around?
Mixed reality lets you see the room, which can help, but nothing replaces telling people you are playing.
Who is responsible if something gets broken?
The terms state you are responsible for your own safety and that of people and pets around you.
