M6 Spartan Laser/Gameplay

Campaign

 * On the level The Covenant on Halo 3, save the Spartan Laser given at the start of the level - or the spare reload lying nearby - for the Brute Chieftain in the Barrier Tower, as one/two hits (depending on the difficulty) should kill it. Hunters and the War Chieftain in the final tower are also good targets for the remaining charge.
 * During co-op in Halo: Reach level The Pillar of Autumn, it is advised to have one of the players to concentrate fire to destroy Phantoms with the Onager while the other player(s) destroy Banshees with the Spartan Lasers, as Phantoms are difficult to eliminate with the laser.

Multiplayer

 * When coming upon a laser pick it up and get to a good/safe spot that vehicles go by often so you can get many vehicle kills. Wasting the laser on single infantry targets is a waste unless there is absolutely nothing else to shoot at on the map.
 * If an enemy is approaching you while you have a Spartan Laser and your death is inevitable, try to waste some of the battery power, so the other team doesn't get too many kills with it.
 * It would be better to use the weapon when hidden as it takes a long time to charge, and the targeting laser sight can be seen from across the map, drawing enemy attention to to you.
 * In Halo 4, having the Ammo tactical package will allow any Spartan Laser the player acquires from a random spawn or a personal ordnance drop to have six shots instead of the standard four. This can be exceedingly devastating on vehicle-heavy maps with excellent sight lines like Ragnarok and Exile.
