Does the reactor main exit have pipes? I think I went the wrong way

Anyway is it possible to go to the main route from beginning? (destroying obstacles)

I must say I didn't apreciate very much these Death Star maps.. the first 3 are entertaining but are the easiest maps in all the game..
About the tunnel run, it seems like the designers didn't have time anymore to test and improve the level. There are bad textures and the most dangerous thing is the stupid invulnerable xwing right behind you..
And if you make a turn and have a look outside.. crappy pixeled plane background.

I almost prefer the 256 color trench run in the old xwing!
