Build and Survive is a Roblox co-op survival game from the group Rainy Creations, where you build a base out of any blocks and parts you like and then defend it from a wave of monsters that attacks at the end of every round. You can play solo or invite friends to collaborate on one shared base, and everything you build autosaves, so your fort is still standing the next time you log in. It is a casual, creative take on wave survival where a smarter build means a longer run.
The game launched in March 2025 and has grown into one of the bigger base-building games on Roblox, passing 210 million visits with over 7.5 million favorites. This guide covers how to play, the build-and-defend loop, codes, and tips for new players, with links to the codes and script pages at the bottom.

How to Play Build and Survive
- Load into the game and pick a spot to start your base, either on your own or with friends on a shared plot.
- Place blocks and parts to build walls, rooms, and defenses out of whatever materials you have.
- Seal up your base before the round ends, leaving no gaps the monsters can walk through.
- Survive the wave of monsters that spawns and attacks your base each round.
- Repair and upgrade between waves. Everything autosaves, so keep improving your fort over time.
Build and Survive Gameplay and Strategy
Build and Survive runs on a simple build-and-defend loop. Each round you get time to build or improve a base, then a wave of monsters spawns and tries to break in. The fun comes from the freedom to build whatever you want, from a tiny bunker to a sprawling fortress, and then watching it hold or fall when the attack hits.
The smart approach early on is to keep it small and sealed rather than big and pretty. A single closed room with strong walls survives the first waves far better than a large base with open doorways, since the monsters path straight to the nearest opening. As you gather more materials, you can expand outward, add extra layers, and reinforce the walls that keep taking hits.
Playing with friends is where the game opens up. On a shared base you can split the work, with one player gathering and rebuilding broken walls mid-wave while the others defend, and the autosave means your group’s fort carries over between sessions. Rainy Creations keeps updating the game over time, adding to what you can build and survive.
Tips for New Build and Survive Players
- Build a small, sealed box first. No gaps means the early monster waves cannot just walk in.
- Use your strongest blocks on the outer walls and keep the weaker parts for decoration inside.
- Block off every ground-level opening, since monsters head for the nearest gap before your walls.
- Build up as well as out. A second layer gives you somewhere safer to wait out a heavy wave.
- Play with friends on a shared base and split jobs, since one person repairing mid-wave keeps the fort standing.
