In Deja Vu if you get all 10 coin flippers correct 2 sets of engineers and enemy groups will not spawn. 3 engineers will still have the consoles but 2 wont exist to hack them putting the mission in a position where it cannot progress. Tried twice and both times it happened we had all 10 coin flippers correct with the same result.
We attempted it a third time racing through and only had about 2 coin flippers correct (by accident) and all the engineers spawned.
Due to testing time I was unable to get an exact threshold where the mission is no longer winnable.
Linear Mode
