The best Lua scripts feature an in-game overlay menu (via GG's UI). This allows you to toggle:

There is no 100% safe exploit. If you use a script, use a "Smurf" (alternate) account. Never use your main account that has purchased skins, as Critical Ops recently started linking bans to hardware IDs (IMEI/Android ID).

A top script supports multiple versions of Critical Ops (0.9.x, 1.0.x, etc.) and works on 32-bit and 64-bit GameGuardian. If a script only works on version 0.8.2, it is worthless today.

These scripts feature a GUI menu (Graphical User Interface) within GameGuardian.
