Through the use of HMT, a new, super gun has been created, and I am here to show it to the world! After much experimentation, an assualt rifle has been modified to shoot grenades!
ALWAYS BACK UP YOUR MAPS BEFORE MODDING!!!
Step 1: Open HMT
After opening up Halo Map Tools, find any map with an assault rifle, and open it up.
Step 2: Switch Projectiles
Scroll down to find the projectiles tab and click on it. Find weapons/assault rile/bullet and press the swap button in the top left hand box.
Scroll down in the new menu and select the weapons/frag grenade/frag grenade.
Step 3: Modify projectile
Change the options in the box on the left to these:
Explode delay#1 0
Explode delay #2 0
Life Span 15
initial Speed 0.3
Final Speed 0.26
Homing Turning 0
Step 4: The End!
Close HMT, open Halo, create a new multiplayer map, and play with the new "Frag Rifle". Then, wait for prey to enter your map and be blown away by your awesome exploding skills.
