Editing Grenade/ko (section)

==Tactics==
*[[welder|Welding]] a door for specimens to break and then throwing many Grenades when the door breaks would most likely kill all the specimens who broke the door. However, if timed wrongly, the door will be destroyed by the Grenades thrown and will not damage the specimens behind it.
*"Stacking" grenades is a good way to kill powerful specimens without expending a lot of resources.
*Dropping a grenade at your feet can be useful when surrounded. It can sometimes kill everything around you while leaving you at low health. Specimens not killed outright will likely be staggered for a short time, giving you an opportunity to retreat. 
*For the [[Firebug|firebug]] at level 5+, being caught in the blast of your own incendiary grenade does no damage at all. This provides a useful tactic for 'pest control' when surrounded by crawlers. Even at level 3 or 4, the fire damage is tolerable, with body armour on.
*The medic's grenade is only useful as a weapon when dealing with masses of weak specimens, so rather than waste them trying to combat a large foe, deploy them among a group of wounded teammates to heal everyone within the area of effect. This means that you can heal teammates from a range without medic guns, and you can heal yourself without using the syringe's alt-fire or the quickheal button. 
*For the medic, deploying a grenade at your feet is amazingly useful, it heals you and damages any zed that is close enough to attack you by melee, and any teammates that come to your aid will also be healed. 
*Some players like to employ 'suicide grenades' in a hopeless situation: dropping all remaining grenades just before death can be a good way to weaken a powerful enemy and help the rest of the group - and to kill as many specimens as possible so that you get more money at the respawn.
*Grenades can deal blunt damage when thrown on specimen. Gibbing any corpse on their way or killing weak ones.
*On higher difficulties like Suicidal or Hell on Earth; where specimen gains extra speed, they can successfully avoid grenades. For preventing your grenade to be wasted, you should kite them a bit towards the grenade by running back. All specimen have a tendency to chase you but when you stand still they'll try and avoid grenades tossed at them.
*Each grenade has a slightly different fuse time it can vary from 2 to 3 seconds which can result in more or less stacked grenades. It is possible with the right timing to stack up to 8 grenades as mid-level support or demo.
*It is possible to throw 2 grenades on one button press for example on X. First open console ingame and type:
 set input x throwgrenade | onrelease throwgrenade
now you can throw 2 grenades fast at one press of x button. Useful for stacking.
