Lets waste no time shall will.

Begining of the game you want to farm or get kills.  Early on you are weak and useless  so play passive and ward pads to avoid being ganked. The key to being a pro marksman is to have patience in farming and landing your skill shots and to know who to focus.

So you want to start of by getting your items and farming in lane as long as you can. One or two potions should help.

Once you get your Soultaker Katana and your Cheetah\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\'s Claw you will be more durable in fights and can out trade your oppenent. Depending on how fed they are in your lane.

The middle of the game is when you need to buy your Atomic Axe. You might be wondering why your not doing any damage it\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\'s because the enemy has already bought  items to negate your attack damage. So your going to need this item for the armor pen.

Late game you should have already be farmed and had team fights where you can buy your Joe Chill\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\'s Revolver and your Velocity 9. Now you  are very dangerous so buy a Ra\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\'s Ghul\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\'s Robe for your last defensive item.  If your really good at kiteing I advise you to get Lobo\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\'s Chain as your last item.

The Amplifiers I use is as followed:

Mods: 250 Credits off(Tier 4) located on page 4/10 optimized Joe
           250 Credits off(Tier 4) located on page 5/10 optimized Velocity
           +9 Attack Damage(Tier 1) located on page 4/10 Enhanced Atomic Axe

Augments: Queen 1.8 Attack 1.5 Critical Page 8/12
                  Queen 1.8 Attack  1.75 Attack Pen Page 8/12
                  Queen 1.8 Attack 1.4 Attack Speed Page 7/12
                  Holt    3.16 Atttack Armor  3.16 Power Armor Page 9/12

Now you might think that these little points dont help they actually do. I hope as the game develop we can put more augments instead of just four. It gives you a little bit of every thing you need to make  those kills count.

Last thing I have to say is Watch out for Batman,Doomdays and Posion Ivy they will mess you up really badly stay as far away from them and kite them with you q w slow combo or Lobol\\\\\\\\\\\\\\\'s Chain. Also in a team fight I know there is a lot going on, but take a deep breath look at who is a open target and focus down the enemies Blasters, Marksmans or  Assassins. Use your  ult which I call the Laser because you can pierce through enemy teams with it giving you long range then ever before. I hope they change Cybrog e to make it a blink. He really needs it because going into a battle with that area of effect slow only get you killed. Do not use that to slow people in a team fight. Only use it to slow the person who is all in your face like Batman.
