With the launch of Blackwoods coming close, I'd like to share a code with you all:
10109090
Entering this in the "Bonus codes" menu will add an extra level to your mission list which will not affect the story but it will add extra context to the events of Blackwoods and show what was happening elsewhere in the world at the same time as the events of Blackwoods.
Please be aware that this code is hard-coded to only work until the end of 2024- after that, the code will change and you will have to find it somewhere else.
There are some codes hidden in the game which will have several effects so keep an eye out for those also!
Release bonus!
