Level 11: The Hard Stuff Rules...
When you arrive you should avoid attacking the aliens in the first couple of rooms. Just head towards the elevator in the middle of the room. Continue to do this until you reach some steps.
These steps need to be traversed before continuing onwards. Once on the other side, just jump down and head to the next room and an elevator beyond that.
Continue upwards until you reach this terminal. After reading it turn left and use the nearest platform to head up.
On the topmost level there's a set of terminals that need to be read. Once read, head back to the previous terminal to proceed to the next level.
