Get through the lurker fort was a mission in The Precursor Legacy that Jak and Daxter completed to obtain a power cell. After opening the gate to the fort, Jak made his way through several obstacles to grab the power cell within.
Walkthrough[]
This mission can only be attempted after opening the gate of the fort using the flut flut. Once the gate is open, you can enter the fort and will find a tall wooden watchtower.
There are two ways of carrying out this mission. The way that it is meant to be done is by climbing the tower and jumping up the wooden platforms to eventually end up on a large structure in the corner next to the entrance. Then, you must work you way around the edges of the fort on the thin pathway made for this mission. There's some slippery platforms, poles and moving platforms as well as a couple of ice citadel bunnies. Half way round, there is a wooden pillar which you activate by pressing a nearby button. If you fall from this point, you may use this pillar to return to the half-way point. At the end you'll find a power cell.
It is also possible to abuse the range of your long jump and simply launch yourself to the power cell's structure from the tall watchtower. Similar shortcuts can also be used to reach the midway point.
