Rainbow's End

The Rainbow's End is an assault weapon that was introduced in the Saint Patrick (Update) and can only be obtained by purchasing the Leprechaun's Pack for. It has a small clip and a slow rate of fire, but in exchange it deals very high Damage. Basically, it is a light version of the Armed Guitar Case.

Strategy
Run And Gun: With this weapon it is a good idea to run all the time. Since the speed of the weapon's bullets is fairly slow, some of your shots might miss the target but the weapon still deals a lot of Damage in a short amount of time. It drains the enemies Health all the way down in a couple of seconds. For this strategy its the best to use 14% Agility and 10% Health equipment or 7% Agility, 10% Health and 10% Accuracy.

Ambush: This strategy is very simple, hide behind corners, 90 degree turns, walls etc. and wait for your opponent to get closer and as soon as they get in your range, take them out by surprise. If preferred, use the Spotter when using this strategy. Always start shooting when your crosshair turns red. For this strategy it's recommended best to use 7% Agility, 10% Health and 10% Accuracy as part of your equipment.

Camping:Do not use this tactic against long range weapon users and in large maps. Find a higher spot with some cover available nearby. Shoot when your enemy comes in sight. And of course, dodge enemy fire. Use Spotter to prevent to get killed from behind. If there are experienced players in the match, do not use this tactic as they may dodge your attacks and kill you when you are reloading.

It's always a good idea to equip parts of either the Cadet Kit, Lucky Fighter's Pack or Leprechaun's Pack.
