All-Points Bulletin(Passive): Whenever an allied champion is slain, Caitlyn gains vision of the killer for a limited time.
Aimed Shot(Q): Caitlyn channels her shot, increasing damage and range over time. If the shot hits, Caitlyn can fire a second shot shortly after, but if it misses, Caitlyn is revealed to the enemy.[Caitlyn channels to take careful aim, gaining @Effect1Amount@% damage and 20 range per second charged. Caitlyn can cancel the charge at any time to reset Aimed Shot's cooldown.] [If Aimed Shot hits a target, it deals @Effect2Amount@ (+@CharTotalPhysical@) physical damage and Caitlyn can fire a single extra shot one second later with half of the bonus damage of the first. [If Aimed Shot misses on the first attack, Caitlyn is revealed to the enemy for 1 second.]

All and all Caitlyn brings a big gun to the field, providing her allies with long range support. Whether she is piercing armor, catching Yordles or sniping a headshot, she is a great addition to any team.

And in the finally:
STAY IN THE BACK. I have made the mistake of trying to go front line (yeah noob right) don't do it you are too damn squishy. Use Brush to charge Headshot and if you are able to hit a champ with it charged without putting yourself in danger do it other wise use the brush and stay back you have insane range you don't need to be up in the mix. As stated in the position line use Brush to your advantage, you are a sniper character after all put trap in front of you in case of someone like katarina or jax jumping in on you so you can get away. This might sound shady but aim for easy kills and/or low HP targets going full out on a full HP tank is dumb people can whine about Kill stealing till they are blue in the face, if they participated but you got the kill they got the assist this is a team game not a solo game without your team you would get rolled and as a Sniper your JOB is to take out the people you can and GTFO you don't run in at try to be a beast. Get the lizard buff as often as you can. This buff is awesome for you and feel free to chew out some ******ed Melee that thinks they need it more than you. With your range and damage this buff is sex in a can +2 The other tip I have is... RUN. you have insane range so you can help a fleeing teammate from max range but plain and simply put you are too damn squishy and if you run into range to help your friend most likely you both gonna die. Don't feed your team to the wolves but Riot gave you the range of the Gods... USE IT

Bulletproof(W):Caitlyn passively resists projectile damage, and can actively double the resistance for a short time. While on cooldown, Caitlyn�¢ï¿½ï¿½s movement speed is increased.[Caitlyn's bulletproof vest helps to protect her, reducing projectile damage by @Effect1Amount@%.][Caitlyn improves her defenses, doubling her projectile damage reduction to @Effect3Amount@%. While Bulletproof is on cooldown, Caitlyn's movement speed increases by @Effect2Amount@%.]

Authority of Law(E): Caitlyn fears an enemy for a short time and is immune to that enemy�¢ï¿½ï¿½s debuffs for a time afterwards. If Caitlyn takes damage from her target during that time, her damage and defenses are improved.[Caitlyn flashes her badge at an enemy champion, causing them to panic in fear for 1 second. For @Effect1Amount@ seconds afterwards, Caitlyn is immune to her target's debuffs, and if Caitlyn takes damage from them during that time, she gains @Effect2Amount@ attack damage, armor and magic resistance.]

The Long Arm(Ultimate): Caitlyn channels for a period of time, then fires a high-speed bullet at a target, getting double the payoff if it kills.[Caitlyn readies her rifle, locking onto and tracking an enemy champion. After channeling for four seconds, Caitlyn fires a high-velocity shot at her target, passing through minions and dealing @Effect1Amount@ (+@CharTotalPhysical@) physical damage if it hits an enemy champion. If this shot deals a finishing blow, Caitlyn receives twice the victim's bounty in gold.]

Opposing Tips
*If Caitlyn�¢ï¿½ï¿½s Aimed Shot misses, she�¢ï¿½ï¿½ll be revealed on the map for one second. Use that brief glimpse to hunt her down.
*When Caitlyn locks on with The Long Arm, you have an very short time after the targetting reticle disappears to get out of the way. Use summoner flash, if you have it.
*Caitlyn�¢ï¿½ï¿½s Authority of Law prevents her target from casting debuffs on her, wait until the effect disappears before trying to stun her.

Character Tips
*Aimed Shot and The Long Arm leave you vulnerable while you channel. Place wards near where you�¢ï¿½ï¿½re charging to keep an eye out for enemies.
*Bulletproof only increases Caitlyn�¢ï¿½ï¿½s speed while it�¢ï¿½ï¿½s on cooldown, so take this into account when trying to escape.
* Use The Long Arm in combination with Caitlyn�¢ï¿½ï¿½s passive in order to finish targets off after a fight.
