A tower defense with a twist – you’re defending a nuclear bomb. It powers your defenses, but the more you use it, the closer you get to meltdown. Manage chaotic engineers, scarce resources and risky upgrades – every decision counts.

So, what is
Last fuse?

Last Fuse is a roguelite city-builder meets tower defense—but with a dangerous twist. At the heart of your settlement lies a nuclear bomb, the only power source strong enough to hold off an alien invasion. The more you tap into its energy, the stronger your defenses become—but push it too far, and the entire city melts down in a fiery catastrophe.

 

Each run is a desperate struggle to expand, fortify, and survive against relentless enemy waves. Gather resources, manage unpredictable engineers, and upgrade your settlement while carefully balancing risk and reward. With permanent progression and a variety of playstyles to explore, every decision shapes your fight for survival.

Features:

1. Defend against aliens

The bomb is your greatest asset and greatest threat. Channel its volatile energy to supercharge turrets, power factories, and unlock devastating technologies. But be warned: the more power you use, the hotter it gets. Keep it stable, or watch everything explode.

2. Balance risk & reward

Tap into the bomb’s energy to fuel your defenses, but let the heat rise too high, and it’s game over. The fuse is lit – how long can you last?

3. Manage resources and workforce

Construct defenses, upgrade technology, and manage a team of chaotic engineers struggling to hold it all together.

4. Customize your playstyle

Unlock and upgrade perks with meta-resources, shaping your strategy with permanent progression after each run.

5. Defeat the mothership

Survive relentless alien assaults, push back the swarm, and launch the Last Fuse on their mothership before it’s too late!

6. Deep below, rare treasures await

Deploy submarines, drill for precious ores, and harness the depths to fuel your war effort. Mine abyssite to craft the highest tier buildings, or radioactive etherium for your bomb?

Reviews

“This game is extremely well made! I really like the concept and the gameplay loop, building and upgrading all the different buildings, turrets etc. reminded me a lot of games like Cities Skylines. The game is very polished and I like the replayability with the different endings, bombs and perks! The artstyle is pretty nice and the music fits this genre of game very well!”
