So, during the last mission, you are required to fly through a long winding tunnel while avoiding collisions. I find it ridiculous and infuriating. I'd like to see how the game ends, but I'm not wasting 30 minutes on the obstacle course. Is there any way at all for me to bypass it?
Nope, you've got to play through it in order to see the end.
If you opt to "destroy the limiters" you have an even longer driving test to pass. I did it, but the clock was down to less than a minute. The "destroy the core" ending is much faster.
You can use your thrusters to boost a bit and get through it faster, though. As long as you don't collide with the walls too much, you'll survive. The first hit knocks down your shields, and subsequent hits will hurt your armor a bit.
I didn't drive especially carefully and made it to the end with roughly half my armor on normal.
The trick to completing that mission successfully is to use a joystick or a gamepad to fly instead of the mouse, due to the cursor follow mouse flight mode fine flying is a lot harder with the mouse.
