Be Quick to get your starting items (DORANS RING MANA POTIONS X2) and get to your lane. Place two turrets horizontal with the torches on your side of the river and one slightly in front. Then sit behind your turrets and farm until level 2. When your level 2 start to make picks at minions with the rockets and prioritise the big minions as they will damage your turrets. as you level up to level 5 start to pick at the opposing champion in your lane but and slowly move your turrets forward to push the lane. STAY IN YOUR TURRETS RANGE INCASE OF GANKS.
As you are reaching mid game you should be aiming to be about half way through your items list. This will mean that you have a good amount of Ability Power so you can start to really push your lane now. Start to move your turrets up more quickly now and make sure they are always in range of each other. As you start to get to the turret leave you small turrets out of range of theirs and use you ultimate and select Q ( press E then Q and place super turret) put the turret right next to the turret and and attack the turret. keep doing this and pus up to their base. If you are getting attacked stay between all 3 turrets and keep replacing them when they die, if you have your ultimate throw down a super turret to help you out and keep firing missiles at them.
At this point you should be reaching the end of your item build and have lots! of Ability power. You should be as a team all middle lane now and pushing their inhibitor turret. When you take this turret do as referred to in Mid Game Chapter and then as you reach the inhibitor place 3 turrets spread around it and it will go down in seconds. It is important that while you are in their base you always have 3 turrets up to use as a bit o defence for your whole team so make your you watch that. Now take the rst of the turrets and !WIN THE GAME!
