A level builder turns a game from something you consume into something you shape. Instead of only playing what the developers made, you build arenas, test them and play them yourself. In mixed reality the idea gets a twist: you are not building on a screen but on your own furniture. This explainer covers why level builders matter and how to make good levels, using the one in Tank Avenger as the example.

Why developers add level builders

  • Longevity. A content pool you can extend yourself does not run out.
  • Creativity. Players enjoy expressing ideas, not just solving others'.
  • Personal fit. A builder can adapt play to each person's space, which is especially valuable in mixed reality, where every room is different.

What Tank Avenger's Level Builder does

According to the game's page, the Level Builder lets you create custom levels designed around your real-world play space. You can place blocks on your coffee table, walls along your sofa and spawn points by the door, then fight in the arena you designed. Your custom levels are saved locally on your headset and belong to you, per the terms.

Why a mixed reality builder is special

On a screen, level design is abstract. In mixed reality, the design problem is physical: where is the sofa, how far is the doorway, how much floor is free? That makes the builder a good fix for the biggest challenge of the format, rooms that differ from home to home.

Principles of good arena design

1. Start with a purpose

Decide what the level is about: tight cover fights, open duels, a gauntlet. A purpose guides every block you place.

2. Make cover meaningful

Tank combat uses walls for both protection and ricochets. In Tank Avenger the Normal Gun bounces once and the Fast Gun twice, so wall placement shapes which shots are possible.

3. Give players choices

Multiple routes beat a single corridor. Leave gaps and flanking paths.

4. Think about spawns

Place spawn points so no one starts in an obviously unfair spot. Putting one by the door is a handy anchor in a real room.

5. Respect real space

Do not design levels that force you toward fragile objects, stairs or cables. Safety beats cleverness.

6. Test and iterate

Play your level several times, then change one thing at a time.

Learning from the built-in worlds

The four worlds are a free design course. City ruins reward medium-range fights. The Desert offers open sand and long sightlines with nowhere to hide from bouncing shells. The Jungle has dense cover, tight corridors and ambushes around every block. The Ice world features slick floors, sliding tanks and shots that keep on going. Borrow those moods for your own arenas.

Ideas to try

  • A "fortress" level with a protected corner.
  • A symmetrical duel arena with mirrored cover.
  • A maze-like corridor level for survival-style play.
  • A level that uses your sofa as the central wall.

Practical notes

Because levels are stored locally on your headset, uninstalling the game removes them, as the support page notes. Keep your play area free of obstacles when testing, and make sure your room setup is current so your arena lines up.

Sharing and keeping your levels

Because custom levels in Tank Avenger are stored locally on your headset, they are private by default and tied to your device. That is good for privacy but means you should remember that uninstalling removes them. If you invest time in a favorite arena, consider writing down your layout in a notebook: where the blocks went, where the spawn points sat. A quick sketch is enough to rebuild it later, and the exercise itself often shows you how to improve the design.

FAQ

What is a level builder?

A tool inside a game that lets you construct your own levels, usually by placing blocks, objects and spawn points.

Does Tank Avenger have a level builder?

Yes. The Level Builder is designed around your real play space and lets you place blocks, walls and spawn points.

Where are my custom levels saved?

Do I need lots of space to build levels?

No. A coffee table or roughly 2 × 2 metres of clear floor can be enough.
