That should explain.
I had this idea a long time ago... and i got to the second last chapter before dying. Now long time later i decided to retry my challenge and looks like i made it.
There were times when i accidently picked up grenades in middle of a battle.
I also picked up a super shotgun but i tossed it away without firing once.
I have the whole thing in .dm2 record but its really slow and boring most of the time.
Worst moment was when i ran into a gunner and my health dropped to 8 instantly, because i forgot to put my powershield on.
So yeah... There are hard parts because its not meant for blaster only, i had to plan few places and improvise a lot.
Also i crashed the game at the final boss first time. When i rejoined it i still had my quad damage and invincibility.
This personal challenge was... mostly boring
Most of the time i was corner shooting enemies. Fun times killing tank commanders without any powerups.
