I have made a suicide machine with about a 66% effectiveness rate.

To those who don't know, in Satisfactory if you have full health you will survive a fall from any height at 1 hp, so for a suicide machine to work from fall damage alone it has to damage you twice.
You walk onto the hazard stripes and get sucked up by the tube, boosted a few times, and get launched down a ramp and through an opening gate, with a chance to hit at the corner of the ramp, impact point 1.
You then get shot down the cliff and either
a. Die on impact if you hit impact point 1
b. Miss impact point and hit impact point 2, automatically sliding off the cliff and falling to your death
c. Miss impact point 1 and 2, and land with 1hp next to the power pole

I could refine this to make it 100% if I wanted to, but I kind of like the idea of some poor bastard who wanted to die and it failed and now he has to figure out what to do with his life
I will make a walk of shame back up the cliff towards the power tower in the future.
