We have recently had to introduce a workaround for the free key system - you will now have to register using the original purchaser's own registration key once you have downloaded from the links below - please ask them to send it to you. If you have been sent account details, you will need to enter them again. Sorry for the inconvenience.

Welcome to Frozen Synapse: you clearly have a friend!

Once you have made your account, you'll need to enter your email address here in order to receive a key to activate the game on Steam.

Steam activation is voluntary - you do not need Steam to run the game.
