Steel Expedition-钢铁远征
A downloadable game
Tank 3D is an offline 3D tank combat game built for macOS. Drive, aim, fire, repair damaged components, manage ammunition, and grow your garage through missions, team battles, boss encounters, and roguelike tower runs.
The game focuses on local play with no account requirement and no always-online dependency. Battles take place across large GLB-based environments, including airport, island, and exclusion-zone themed maps. Between battles, you return to the garage to repair components, manage ammunition, open loot crates, and prepare your next run.
Current features:
- Offline macOS App.
- 3D tank driving, aiming, firing, hit detection, damage, and destruction.
- Training, missions, team deathmatch, capture the flag, boss fights, and roguelike tower mode.
- Garage progression with coins, ammunition, repairs, inventory, crates, and tank fragments.
- Component damage for tracks, engine, turret ring, gun breech, and ammo rack.
- Three large GLB battlefield themes.
- Experimental LAN multiplayer support.
- Prototype level editor for custom mission drafts.
This is an Early Access build. The core game is playable, but content, balance, visuals, performance, and mission design will continue to improve.
