Sigma Theory – Mini Review!

What is it?

Sigma Theory is a casual, indie espionage game that sees you playing as the head of a shadowy government organisation comprised of a number of spies. Your task? Get ahead of the rest of the world in the field of Sigma, by hook or by crook.



Espionage is cool.
Lots of different spies to use.
Always different.
Couple of bugs.
Some underdeveloped features.


A couple of bugs let Sigma Theory down, but overall it’s very enjoyable. It mixes all the elements of a fun game into a casual experience, which means you can drop in and out as required. Well worth it.
