A category I request is Mirror Mode. There is a full game on Roblox.

i'll talk with the other mods about this, and i'll post if we think adding is a good idea

main problem I have with your request specifically is the separate game for it using sr4c instead of sr4 and this is an sr4 board but there could definitely be a category for the mode within sr4 itself. I'll put it up to vote later today and see what the community thinks, there's a good chance this will be added as a category. :)

Thanks for checking it out it'd be cool to see where this awesome community takes this.

Also if you get 60 stars (finish 2 dimensions) there is actually MIRROR MODE inside SR4.
