I have discovered that while using Enable Cheats command allow you to summon things in multiplayer, it only summons client-side, and no one else would be able to see or be affected by it, and not even you btw. So I invented this thing that replicate the Summon and GiveWeapons command, EXCEPT NOW IT WORKS IN SERVER

Summon is replaced into SandboxSpawn, while GiveWeapons is replaced by Gimme. The syntax is the same. This little gametype will turn your Renegade X server into a sandbox mode, all you need to do is put the file into this directory
[your Renx directory]/UDKGame/CookedPC/
Then put these parameters in the server Target box in the properties
?game=Rx_Sandbox_Game.Rx_Sandbox
In my test, the server manages to spawn in the actors server and client-side. The server gives collision and damages and allows you to drive the summoned vehicles. Weapons also works well. They're actually summoned to your inventory
Warning : Your buildings can still be destroyed. The internal modifier is still WIP and the included mutator doesn't work as of now. There is also no way to delete your summoned objects. Do not overdo it
