Block Bastion

Command the last bastion and hold the line! Block Bastion is a fast, colorful voxel tower defense game where a relentless machine army pours down the canyon toward your Command Core — and only your turrets, walls, and quick thinking stand in the way.

Place towers along the path, build walls to bend the enemy's route into a deadly maze, and upgrade your defenses as the waves grow stronger. Every kill pays coins. Spend them wisely.

FEATURES

• Five distinct towers, each with a job:
- Cannon — heavy ground damage
- AA Gun — the answer to enemy flyers
- Missile — splash damage that hits ground and air
- Tesla — shocks and slows ground packs
- EMP — slows aircraft for your gunners

• Build and strategize:
- Raise WALLS to block and re-route the enemy — and mount turrets right on top of them
- Build MINES for steady coin income
- Unlock Missiles with a Factory and tower upgrades with a Lab
- Upgrade any tower up to Level 5 for serious firepower, or sell for a refund

• A real campaign:
- 20 levels across 60 escalating waves
- Ground convoys AND overflight air lanes — you must cover both
- Late waves shoot back and can destroy your buildings (walls hold firm), so placement matters

• Easy to learn, satisfying to master:
- Simple double-tap placement
- A guided tutorial gets you started in minutes
- Chunky voxel visuals with punchy explosions and effects

No timers, no energy bars — just pure tower-defense strategy. Set your defenses, send the wave, and watch your bastion light up.

Can you survive all 60 waves and keep the Core standing?

Block Bastion is free to play. An optional one-time purchase removes ads.
