I would like a leaderboard where the players are required to abide to the following limitations:

• No grenade launcher.
• No shooting through walls; targets must be in player's view.

I have a decent run under these limitations that I would like to submit into this website, at least to get my name on the board somewhere.

You've posted this same exact thing before. Your limitations basically defeat the purpose of a speedrun, so the answer won't change. This isn't something that is going to be added

Alrighty, understandable.
