While writing out a more detailed description of the behavior, I stumbled upon the solution myself.
When you try to install the game over the internet, just let it start, and then cancel it. This will both remove the installation and download from the queue, but apparently also remove the knowledge of the installation from the Xbox One.
So:
- Start the online install
- Cancel it
- Return to the home screen
- Notice that the disc tile has now changed to "Install disc"
- Activate the disc tile to start the installation from the disc.
This worked, the game now installs from the disc. Obviously any downloaded DLC's will still need to be downloaded, but for the purpose of this question this is not relevant.
Now, what do you do when you get back home and want to plug in the external drive?
Here's what I did. I first uninstalled the game using the storage management.
This makes my Xbox One forget that I had the game installed. Make sure you don't delete any savegames you have on the console.
Then, you turn off the Xbox One, plug in the external drive, and turn it back on.
Once you do that, the disc tile still says "Install disc". Ignore that. Instead either use your pinned link to the game, the tile for the game (if it shows up on the home screen), or navigate to your games and apps list and activate it. You should get a message saying not to unplug the external drive, and that your game will be ready soon.
A few seconds later you can try again and the game should now start.
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.
Best Answer
Dragonrage is pretty spot on there. To bring the communication window up press ↓ on the D-pad and while holding that down, use the Right Thumbstick to scroll in the direction of the option that you want to activate (in your case, ↖ for "Thank" and ↘ for "Group Up")

To activate the action, release the ↓ on the D-pad while staying hovered over the option with the thumbstick.
I have occasionally found the timing of releasing the D-pad will just cause the menu to disappear and nothing to be activated, so make sure that you are still pointing in the correct direction with the Thumbstick when you release the D-pad.
