The game currently has two snipers and they work differently.
Widowmaker
Widowmaker has a grappling hook that she can use to pull herself up to ledges and rooftops. You should use this to position yourself somewhere where it's hard to see you.
Her alt-fire will use her zoom scope. When zoomed in, a power meter appears on your screen. When the power meter is full (takes about 2 seconds), headshots will do 300 damage and body shots will do 150 damage.
Keep in mind that a few characters have a different head position:
- D.va's head is...
- Mech: The entire cockpit she sits in.
- Girl: Her head
- Bastion's head is...
- Recon configuration: His head
- Sentry configuration: The glowing spot on the back of the turret near the top.
- Tank configuration: The glowing spot on the back of the tank near the top. (This used to be at the top of the tank, but I'm pretty sure that changed during beta.)
Bear in mind that death replays as well as your sniper rifle's tracers (the red lines that show where you were shooting) give away your position, so you periodically need to move.
Don't forget to set your venom mine down somewhere. It's best use is as an early warning that an enemy is nearby as it shows on your screen when it's triggered.
Your ultimate should most likely be used shortly after you get it as it shows all enemy positions to your team.
Hanzo
Unlike Widowmaker, Hanzo doesn't have a zoom scope. As such, you tend to do better when you're closer to an enemy. Constant movement between shots helps quite a bit.
Remember that you can climb walls and use this to your advantage.
Hanzo's arrow do more damage if you charge the bow for a second before letting go of the attack button.
You should use your Sonic Arrow whenever it's ready to help show your allies where enemy players are. Keep in mind that, unlike Widowmaker Ult, it only shows enemies near the arrow.
On Defense, consider shooting it at one of the enemy doors during setup time so that you can see what heroes the other team has.
Your Scatter Arrow is a mixed bag. It's most powerful when shot in a small room as the shots ricochet off walls. However, you can still do a lot of damage with it by shooting the floor directly in front of an enemy.
Your ultimate is incredibly powerful as it sends the twin dragons/wolves in a direct line in front of you and travels a good distance, but bear in mind that it won't hit anyone within about 5 meters of you.
I believe the visual bug from the PTR is present in the live version of the game. I have also seen the Top 500 symbol where my rank should be, and I know for a fact that I am not in the top 500 players in ranked mode (low 50s).
The Top 500 should be determined rather intuitively: the 500 players with the highest ranking, including fractional ranking amounts. Jeff Kaplan has stated in this post linked below that they will not begin displaying the top 500 players until a few weeks into the season, so I think it's definitely bugged.

In Lucioball, you are trying to get the ball into the opponents goal, while preventing them from scoring on your team's goal. There are two teams of three Lucios each, with a slightly different moveset from a normal Lucio.
Instead of the projectile ability, each Lucio's left click ability is replaced with a punch which is used to hit the ball. Lucio's right click ability functions as normal, and functions as a strong knockback on the ball.
Lucio's Amp It Up also functions as normal, except it only affects the player who uses it, instead of all team members in sight. The biggest change is in Sound Barrier. Instead of providing shields, Sound Barrier pulls the ball towards the player who uses it.
As to the glowing spots on the field, these are jump boost pads. As long as you are standing on one of them (including the ones around the goal) you can jump extremely high.
