Mod Menu 2.1 — Gd

Originally designed for creators, its "2.1 Mod Menu" includes the best level editor enhancements: Multi-Select, Copy/Paste triggers, and Instant Object Placement.

Six months later, a modder named "PhaseReverse" found a new file buried in the GD servers. It wasn't a mod menu. It was a log—thousands of entries, each one a player who had installed Mod Menu 2.1.

Its "Pro" versions became the industry standard for top players to verify "legit" completions using the Cheat Indicator0;4e3; and detailed Noclip Accuracy metrics.
