Block Bastion

Defend your command core in a fast portrait tower defense game with tactical builds, upgrade choices, and escalating enemy waves.

Block Bastion is a portrait tower defense game built for quick, tactical battles.

Defend your command core against waves of enemy vehicles and drones. Build cannon, tesla, EMP, anti-air, and missile towers, then reinforce your base with walls, mines, factories, and labs. Every wave asks you to spend carefully, place defenses well, and adapt before the next attack arrives.

Features:

• Portrait-first tower defense gameplay
• Multiple tower and structure types
• Upgrade and sell decisions during battle
• Ground and air enemies
• Wave-based progression
• Tactical base building with limited resources
• Optional rewarded boosts and remove-ads purchase

Hold the line, protect the core, and build a bastion that survives the assault.
