There are multiple ways of completing this game. In addition to three difficulty settings you can play this with a single commando (letting the other die) or trying to complete it with both or doing it as a 2-player co-op. Also, you could do runs with etc. knife only as stealth is an actual mechanic in the game.

If someone wants do run the game differently in a way that still makes sense as a speedrun, I'll add the appropriate category once there's a run to submit.
