I just thought I would quick rant about one of my favorite weapons in this mod, the grenade. You have the ability to 'cook' the grenade by holding down the fire button. By doing so, you can time your grenade to blow up at the right moment if you play it right. I've gotten really good at doing this, resulting in KillerMonkey swearing over his microphone at me.
Alternatively, if you like to play dirty, you can continue to cook the grenade and blow you at your target up without throwing it, assuming you are near them. You are damaging your score, but it can be fun and sometimes you get some great responses over the mic.
