I made many changes to the server side to get the following things:

• 4096 or more up to 16384 entity limit.
• 4096 visible entities, while previously there were only 256.
• different func_breakable and their limit of 4096
• weapon limit of 8192 weapons
• physics, objects push each other, take damage from collisions and can float and lie on each other and fly beautifully
• many built-in functions and removed unnecessary code
• NPCs, entityplus code with my feature save and load for Big maps
• NPC groups such as citizen, enemy etc, they react to each other differently, and not all communicate with the player
• multiplayer support for entityplus and more things maded by me

also rewrote the client part to add hud customization, player customization and a beautiful hud and good fonts

also made a scripting language that works in 3 spaces, game, cgame, ui

the scripting language can create interfaces in ui.qvm at the moment, and it is easy like .cfg files.

if you have any questions or any tips on modding, i can help you with modding quake 3 or making mods. :)
