Fog
I Wanted that to be added and it would really be useful for some zombie maps.
Rain
Just like the snow in PB2 but with a rain sound you can also enable or disable thunder sound in Level Editor
Buzzsaw
If players or enemies touch it, It will brutally break the body of the player/enemy ( You can also change the damage too )
Now the best thing is
When we play an approved map for after 10-20 minutes it will automatically end the match and it will teleport's us to a new random approved PVP map just like the counter strike games but we can disable it when making a new match and if you disable it then the map will stay until all players leave the match.
that would be a cool concept.
