Let's Do It...

Alright here is those concussion grenades from Team Fortress with some things added in. This code is not taken from the Team Fortress source code at all and is total written new by me, John Rittenhouse. SO here we go. Also make notice I set my grenades up so they can be killed so make sure you do that tutorial I forget who did that one but thanx.

Okay open up "g_weapon.c" now add at the end this code.
