Grenade spamming

Grenade spamming is the act of repeatedly throwing grenades into an area. In some cases, grenade spamming is used for tactical reasons; however, it is commonly considered a Newb tactic.

Description
Grenade spamming is used to deal large amount of damage in a fairly large area in a short time. Grenade spamming has a similar effect to an artillery barrage, and can turn an enclosed space into a deathtrap. Frag Grenades are often used to spam around corners and to deal greater damage; Plasma Grenades are used when spamming a target head-on. Most grenade spammers use grenades to weaken opponents, finishing off their weakened and unshielded foes with standard weapons.

Grenade spamming is frowned upon by many players. Widely considered unfair and a "noob" tactic, grenade spamming does not require a significant level of skill or aim. This tactic is also considered "noobish" in campaign for the same reason, though on harder difficulties it can prove to be extremely useful.

Tactics
Grenade spamming works best in narrow and confined spaces, where it is more difficult to escape a grenade's blast radius. It works quite well on smaller maps for the same reason. Grenade spamming can also be used to cover an escape, distracting or killing foes when the spammer's shields are down.

While combating Flood in enclosed spaces such as corridors, the Frag Grenade can be an effective way to destroy many Infection Forms from the blast. It is also useful to clear areas of Flood, as killed Flood drop plasma grenades which will cause a chain reaction from the thrown Frag Grenade.

An aspiring grenade spammer should use the Plasma Grenade when attacking opponents head-on, and the Frag Grenade when spamming from around a corner. On large maps, blindly throwing grenades in the general direction of an enemy base can sometimes result in wounds or kills. On large maps, grenades can also be used in place of anti-vehicle weapons such as the Rocket Launcher to destroy enemy vehicles.

Etymology
The term "grenade spamming" is likely derived from the act of sending E-mail spam. E-mail spam refers to unwanted and unsolicited messages that are repeatedly sent to a recipient.

Trivia

 * Many players frown upon grenade spamming, due to the lack of aim and skill used.
 * In Campaign on Legendary, Grunts will often throw four or more grenades in a row at the player, and maybe twice as much with the Catch Skull activated.
 * This is especially rampant in Halo 3, as the textures of the maps cause the grenades to go into random directions.
 * This tactic is used far more often in Halo: Combat Evolved and Halo: Reach because the power of the grenades is greatly increased.
 * In Halo: Combat Evolved, one of the custom game options is for unlimited grenades.
 * In Halo: Combat Evolved Anniversary, the Bandana skull gives the player infinite ammo and grenades.
 * In Halo: Combat Evolved Anniversary, grenades were often found in groups of 4 due to that being the max allowed in that game. Interestingly though they did not increase the grenade count to 4 in the Anniversary Map Pack for Halo: Reach.
