Totally Defenceless

Totally Defenceless is a tower-defense game about repelling an alien bug assault on Earth. You build towers to protect energy cores from endless waves of insects, using tower placement to influence the routes enemies take across each map.

Build your defences

You can choose from hundreds of towers. Their placement shapes the paths enemies are likely to follow, so your layout is central to defending the cores. Laboratory abilities can disrupt an attack or deal with enemies that survive your towers.

Face the alien bugs

The insects have special abilities, work well together and attack in waves. Many campaign locations also have their own features that affect the battles.

Campaign and progression

Permanent unlocks add options and strategies that you can use on previously played maps. These can help you earn rewards that were out of reach or pursue higher scores. A map can take from 20 minutes to multiple hours to complete, depending on how well you survive; completing the game is likely to take at least 40 hours.
