Call Of Duty 5 : World At War
Primary Grenades x2 is a Tier 1 perk in Call of Duty: World at War that gives the player two frag grenades, sticky grenades, or Molotov Cocktails. This is useful if you rely on grenades for kills. It is unlocked at level 44. (Not to be confused with Frag x3 from Call of Duty 4: Modern Warfare, which gives you threefrags, instead of 2.) A likely reason for the reduction is because there are different types of grenades other than frag in World at War, also the number of grenade-related deaths in Call of Duty 4 were staggeringly high.
This perk is useful in taking down a group of enemies as two grenades ensure that most, if not all, are eliminated. Although, whoever has the perk tends to not cook the grenades, making it easier to dodge the loose grenade. This perk is looked down upon due to the fact that if anyone is damaged by the first grenade, will most likely be finished off by the second, creating irritation (This is also called Grenade Mortaring or 'nade Spamming). It is also advisable to not use this perk in Hardcore modes due to random grenade throwing usually results in a team-kill. A good tactic is to throw a Smoke grenade, or a Tabun Gas Grenade into an enemy building then launch the two grenades. Chances are you will get a kill, especially if you let them cook for a few seconds.
