Well, the Empire doesn't consider a small one-man fighter to be any threat, or they'd have a tighter defense. An analysis of the plans provided by Princess Leia has demonstrated a weakness in the battle station. But the approach will not be easy. You are required to maneuver straight down this trench and skim the surface to this point. The target area is only two meters wide. It's a small thermal exhaust port, right below the main port. The shaft leads directly to the reactor system. A precise hit will start a chain reaction which should destroy the station. Only a precise hit will set off a chain reaction. The shaft is ray-shielded, so you'll have to use proton torpedoes.
This teaser of the trench I built for the event.
Ricecracker's fighters will be flying down it soon... pew pew pew sounds to be provided by me.
