To complete the Tight Squeeze Challenge in Lego Star Wars: The Skywalker Saga, you really want to find an easy route by means of the Protocol Terminal during the Ground A-salt level in Episode VIII – The Last Jedi. Curiously for a level Challenge, Tight Squeeze can’t be finished while playing in Story mode, so if you need to get it, you’ll need to finish the level no less than once, then replay in Free Play.
The level starts with you playing as Luke Skywalker (Old – Crait) and secured fighting with Kylo Ren, yet this piece of the level is minimal in excess of a QTE (speedy time occasion) manager fight. You really want to divert Kylo Ren to finish the Ground A-salt level and finish Episode VIII – The Last Jedi, yet the meat of the level happens inside the Crystal Cave.
How to find an easy route through the Protocol Terminal in the Ground A-salt level
Halfway up the steps toward the west of the focal point of the Crystal Cavern, there’s a Protocol Terminal. Change to a Protocol Droid (for instance, C-3PO) and utilize the terminal to oversee C-3PO (Rusted). Go down the steps (as Rusted C-3PO) and utilize the Protocol Terminal to get the secret phrase for the Crait Service Tunnel Doors. Proceed to the lower part of the steps, go past the box with gold bars, and access the red Protocol Terminal. Input the Crait Service Tunnel Doors secret phrase here and the Crait Service Tunnel Doors will open, making an easy route through to the Emergency Doors and finishing the Tight Squeeze Challenge.
Completing the Tight Squeeze Challenge is particularly significant, as it opens up the piece of the Ground A-salt level that you want to access to finish the Knock Challenge, and to gather each of the five of the Minikits that can be tracked down in the Crystal Cave.
