I am you Super Phun Thyme!
So, most of you veterans might remember this awesome glitch, but I thought it would be nice to share it with the new generation of Halo players who didn't start their Halo career with Halo CE 10 years ago.
The glitch is what makes infinite ammo a possibility, works on every level and only requires an other weapon on the ground.
[Note] This glitch only works on weapons that use ammunition. It doesn't work on plasma weapons or shotguns.
Also, it requires you to have at least some rounds left in store.
The key is to reload and the moment you start to reload, swap weapon with the one on the ground. If you have done it right, you should hear the gun finishing reloading on the ground, and a second after a subtle click sound will be heard, now swap back the weapon and there you have it! It will magically have reloaded itself without expending ammo!
In this way, you will be able, for example, to keep your beloved rocket launcher or pistol for the entire run of Assault on the Control Room, just remember to have a weapon to swap near you.
I hope this will be helpful for some of you and it also helps a lot when playing with famine skull or the skull where you lose twice the amounts of bullets.
Cheers,
Ibex
