Fallout Tactics

Note

 * Frag Grenade is primary weapon for grenadier character throughout most of game. Decent damage, and abundance allow it to be used often and indiscriminately. However, it`s recommended to have a sniper character ready to provide cover and long range support, since the AP cost of throw is quite high.

Fallout 3
The Frag Grenade is the first type of grenade you'll find in the game (check the first blue Mailbox as you come into Springvale from Vault 101) and is commonly carried and used by melee equipped raiders and super mutants. While it's unlikely to kill you by itself it can do a lot of damage in one hit and has a high chance to cripple arms and legs. Its blast radius is small compared to grenades you'll get access to later (such as the nuka grenade or plasma grenade) but it can still be useful against multiple attackers if they're bunched together at a pinch point like a stairwell or doorway.

The in game physics for grenades are quite realistic which means throwing "up" a stairwell or hill means they'll most likely just coming rolling back before detonating next to you. The plus side is you can throw them through doorways or bounce them around corners to attack enemies you can't see. Be careful trying to throw them through windows though as, if they hit anything they'll bounce back at you.

The Frag Grenade appears to be based on the Danish Håndbombe M/23, only it has grooves (ala the Mk 2) on the middle of it.

Tactics and strategies
All tactics and strategies for the use of the frag grenade have been moved to the discussion page of this article. It can be accessed by clicking on the discussion tab at the top of this page.

Traps

 * It is common to find several grenades hanging on a string from the ceiling. These are called a grenade bouquet and will be activated with a tripwire and will explode on a timer. The bundle of grenades can be disarmed with a high enough explosives skill or can be shot down (this will cause them to explode). If you do accidentally activate the tripwire try to run out the area as the grenades are on a timer. Note that these grenades won't show up as red arrows.

Bugs

 * The "Rocket-Boots-Bug": there's a semi-common bug with deathclaws, behemoths and giant radscorpions. The explosion may launch them into the sky, which is fine, if a bit comical, but can lead to multiple queued VATS shots wasting grenades and AP (exploding harmlessly under them). It's probably best to setup one targeted throw at a time. Or use the more common approach to fighting "big nasties": one grenade to cripple it then mop-up with small arms fire.


 * Destroyed grenades i.e targeted in V.A.T.S. and shot out opponents hand, have a condition of zero yet you can use other broken grenades to fix them thus restoring its firepower.


 * When a missile launcher is broken from launching a missile, if you have one grenade/mine of any particular type in your inventory, e.g. having one frag grenade but any number of other grenade/mine types, and it is the next weapon you equip, you will have unlimited ammo for that particular grenade/mine until it is unequipped. The next grenade/mine thrown after the first will be invisible while held in the player's hand but will appear once thrown. This is an excellent way of obtaining many bottlecap mines as they can be disarmed and picked up, adding them to your inventory to be used at any time. VATS, unfortunately, cannot be used until the grenade is unequipped.
