Any time the last cube in a column is removed from the Tesseract, an Event icon will be revealed on the Base Plate. Trigger the effect of the revealed Event immediately. Most often this will occur after Priming a cube, however it can also occur in the Action phase by removing the last cube from a column.
The Events printed on the Base Plate are all dangerous, but some are far worse than others. It is wise to delay revealing them as best you can. The Base Plates offer four levels of difficulty, determined by the type of Event icons printed on them and the frequency of the harsher Events. Here are their effects:
ACCELERATE: Destroy the lowest removable cube on the Tesseract and place it aside or in the box. While the least dangerous, destroying cubes hastens your end.
FORTIFY: Reroll the lowest Primed cube in the Primed Area. The danger here is that rerolling a cube may cause a Breach you didn't see coming.
CHAIN REACTION: Prime the lowest removable cube on the Tesseract. Yes, this means repeating the process and can potentially reveal other Threat Events in succession.
FISSION: Prime the lowest removable cube on the Tesseract AND Prime 1 random destroyed cube. Instantly adding two more cubes to the Primed Area can be devastating. Compensate by keeping the Primed Area as clear of cubes as you can when Fission is listed on the Base Plate.
EMP WAVE: Choose a Lab to safeguard. Reroll all cubes in each of the other Labs. This can undo sets and runs you have been putting together - but occasionally, it can work to your benefit.
EMP BLAST: Reroll all cubes in ALL Labs.
INTERPHASE: Primed cubes with EVEN values Adjust up by 1. A very dangerous event, as it can immediately cause one or more Breaches. You will have to manage the Primed area even more carefully than usual.
SHOCK WAVE: Destroy all cubes in ALL Labs that match the VALUE of the newly Primed cube. Any cubes that match the number rolled are Destroyed, regardless of the color. This can be devastating.
