I was wondering if it's possible to do weapon-only runs like assault rifle, spread shot, flamethrower, and rocket launcher-only runs?

I was thinking it would be interesting to see if you can beat the game by just using only one weapon. Spread shot and Flamethrower are available on mission 2 while rocket launcher is available on mission 3. So for those runs, you use the assault rifle until those weapons become available and stick with that weapon.

I want to do some runs with just a specific weapon, and it would interesting to see how fast it would be.

How about we add a Rifle-only category in the first instance (so no crash bombs or other weapons)? I'm just hesitant to add loads of extra categories that may be left with very few runs.

I didn't think not using crash bombs would be considered not for runs like this, especially since they're heavily needed for many parts of the run.
