### Initialize Game Entry Point - Lua

Source: https://context7.com/azureedev/payday-2-luajit/llms.txt

This Lua script determines the game's entry point based on global state flags, selecting between NetworkGameSetup, MenuSetup, or EditorSetup for initialization. It requires the 'Version' utility and dynamically loads the appropriate setup class.

```lua
-- lib/entry.lua - Game initialization entry point
require("lib/utils/Version")

local selected_setup = nil

if Global.load_level then
    -- Multiplayer heist session
    selected_setup = require("lib/setups/NetworkGameSetup")
elseif Global.load_start_menu then
    -- Main menu
    selected_setup = require("lib/setups/MenuSetup")
elseif Application:editor() then
    -- Level editor mode
    selected_setup = require("lib/setups/EditorSetup")
else
    -- Default to menu
    selected_setup = require("lib/setups/MenuSetup")
end

setup = setup or selected_setup:new()
setup:make_entrypoint()

```
