But it was only a few days ago that finally, after six years, players found a secret race involving mongoose four-wheelers.

Patrick Wren, a multiplayer designer at 343, tweeted that inside Halo 5's mission “Evacuation” there is a hidden mongoose race that can only be triggered with four players in co-op.

This caught the attention of the Halo community and soon players went searching for this undiscovered secret.

Various Halo YouTubers and secret hunters began searching the entire level for any hidden switches, sounds, etc.

Finally, after some extra hints and nearly two days of hunting, Halo 5's hidden mongoose race was activated.
