Build Ur Base How to Beat Wave 100 & Unlock Chapter 2 Guide!

Reaching wave 100 in Build Ur Base is a major milestone because it unlocks Chapter 2, where the game gets tougher and introduces stronger blocks, weapons, and enemies.

Many players get stuck around the higher waves because their defenses aren’t optimized, but with the right strategy, you can push through and clear wave 100 without wasting time or resources.

This guide will walk you through the best setup to survive, what defenses to focus on, and how to prepare for the big jump into Chapter 2.

1. Build a Strong Frontline

At the start, most enemies will approach from the front of your base. Rarely do they attack from the back or sides, so putting your resources into the frontline wall is the smartest move.

• Use basic blocks and cheap decor as shields early on.
• Gradually replace them with metal blocks as you progress.
• Keep multiple layers of walls so bosses don’t break through too quickly.

2. Prioritize Cheap but Effective Weapons

Weapons can get expensive, and many players waste money chasing rare ones from crates. Instead, focus on affordable defenses that scale well into the later waves.

• Crossbows – cheap and reliable, stack them in rows behind your wall.
• Turrets & double turrets – great for mid-game damage.
• Flamethrowers & Miniguns – more expensive but extremely powerful if you manage to buy them from the shop.

Quantity matters more than quality in Chapter 1. Filling your base with dozens of crossbows will often work better than relying on one or two rare weapons.

3. Use Spike Traps Strategically

Spike traps aren’t mandatory, but they help reduce pressure on your walls.

• Place them in front of your main defense line.
• They work best against small enemies while your turrets focus on bosses.
• Don’t over-invest—just one or two rows is enough.

4. Take Advantage of Range

Many weapons, like crossbows and flamethrowers, can shoot through walls. This means you can safely place them behind your defenses without worrying about blocked attacks. Use this to maximize damage while keeping weapons protected.

5. Upgrade in Layers

As you get closer to wave 100, bosses hit harder, so it’s important to layer your defenses.

• First row = durable blocks (metal or decor for extra HP).
• Second row = spike traps for small mobs.
• Behind walls = rows of turrets and crossbows.
• Higher levels = more turrets stacked for extra firepower.

6. Always Farm & Shop Smart

• Shop resets every 5 minutes, so keep checking for cheap blocks and turrets.
• Use the auto-wave and speed-up function once unlocked to farm faster.
• Gold Rush crates give bonus coins—grab them whenever they appear.

7. Beating Wave 100 & Unlocking Chapter 2

Once you survive wave 100, you’ll be teleported into Chapter 2. Here’s what changes:

• Stronger blocks like magma and mountain blocks become available.
• Your old best weapons in Chapter 1 become weak compared to new ones.
• Enemies are stronger, faster, and require better planning.

To prepare, make sure by wave 100 you already have:

• A multi-layered wall setup.
• At least some miniguns or flamethrowers in your build.
• Enough coins saved to start buying stronger blocks in Chapter 2.

Reaching wave 100 in Build Ur Base is all about layered defense, smart weapon choices, and consistent farming. Focus on building quantity with crossbows early, reinforce with turrets and flamethrowers later, and always keep your frontline solid.

Once you unlock Chapter 2, be ready to adapt—your old defenses won’t be enough, and you’ll need to invest in stronger blocks and weapons. If you can hold out until wave 100, the challenge of Chapter 2 is waiting, and that’s where the real test of your base-building skills begins.
