LADDERS
Through out ace of spades I always wanted to get up something without making stairs, this would be more efficient, and very handy.
SIGNS
I really want signs in the game, instead of telling people there's a tunnel, you could place a sign. Instead of making stupid markers, you could place a sign down. Please note that you can write anything you want on the sign
DOORS
Doors would be very handy on the game, but if you're thinking what's the point of having doors here's why:
1.Only your team can open doors
2.Opposite team takes 5 bullets and 10 spade hits to destroy doors
3.You only get one door, this will prevent blocking other teams tunnels
TNT AND PRESSURE PLATES
In the game, I always wanted to make traps with TNT:
1.TNT will create 3 time as much explosion radius
2.TNT can not be shot at to ignite
3.Stepping on a pressure plate will activate TNT
4.Only the opposite team can activate TNT, this will prevent griefing
5.You can destroy TNT without it blowing up, this will prevent blocking other teams tunnels without them dying
6.Only get 1 pressure plate and 2 TNT
That's it enjoy ;)
