EMP Grenade

Explosive Type EMP
Explosive Power Varies
Damage Radius 8
Carried By Engineer
The EMP grenade is a serious contender for the most devestating grenade. Though it has no explosive power of its own, it detonates anything explosive you are carrying. Thus, if you are a soldier, it will detonate all the rockets and explosive shells, ie shotgun shells, you are carrying. This basically makes it devestating against most classes, as even the lightly armed scout still carries enough explosives to make sure you can take them out. The only effective defence against this grenade is to make sure that you have discharged all your ammunition - you will basically become invulnerable to this grenade - in practise this rarely works though as it can take a while to use all your ammo and that will leave you defenceless - also, all you have to do is run over an ammo pack and you are back to square one and vulnerable.

A more advanced technique in their use is for the engineer to drop a couple of ammo packs around where they intend to detonate it. Even if you are carrying no explosives, the ammunition in the ammo packs will explode around you and that is likely to spoil your day. Another use for them is that they blow up demomans pipebombs so you can greatly help your team by clearing pipebomb traps - remember though that they also blow all pipebombs, including those laid by a demoman on your team so avoid blowing up your own demomans pipebomb traps. If that is not enough, these grenades work through walls and ceilings. Basically, these grenades are lethal to pretty well anybody and if used well will definitely spoil your day. This does make them a spammers delight though so if you're an engy and a spammer then STOPPIT. Please.
