Operation Patchwork

Incoming — Commander Shepard

Five transmissions came in overnight — all from friendlies, all scrambled with a Caesar cipher. That's an encryption method that shifts every letter a fixed number of steps through the alphabet. 'A' becomes 'D', 'B' becomes 'E', and so on. Julius Caesar used it. It's 2,000 years old. And people still get fooled by it.

You have the key. The alphabet reference on each screen shows you exactly how to decode it. The enemy is intercepting the same signal and working to brute-force the pattern. They're fast. You need to be faster.

Five messages. Decode them all before the clock runs out. Every wrong keystroke is data you're handing them.

Prove you belong in the field, Agent.
