In Uprising, the main mode that you can obtain all but 1 of the achievements, you can select 1 of 4 heroes.
Each of the heroes have all the same abilities as they do in normal player vs player game modes. Their damage and health pool is also the same. The only thing different is that the game applies their Uprising event skins, regardless of whether or not you own them.
Reinhardt: Your shield is invaluable within this mode. You need to be aware of when Bastions spawn and always keeping an eye out when the Detonators spawn. If your team hasn’t had enough time to take down the detonator, you can either shield (preferable) or charge it away as it’s exploding. The herder the mode, the more you’ll need to shield. If someone dies, use your shield to protect whoever is possible to revive the fallen Hero.
Torbjorn: Your turret should be put in a position where it will attack the most amount of Nullsector units. This isn’t the time to get cute with the turret and put it on the side somewhere. It needs to be up front and sharing some of the damage. While you’re hacking, the turret needs to be on point, generally somewhere either side of the terminal. During the payload phase, it needs to be on the payload. Do not put the turret to the side, this will put unnecessary pressure on the other members of the team. At the end, you need to have it so that it shoots down the corridor, meaning you’ll need to rebuild it a few times.
Mercy: Along with healing, your main job is to boost Tracer. The harder the difficulty, the less you’re using your pistol, even though it does a surprising amount of damage. Where possible, save resurrection for when someone dies and you can’t get to them, otherwise revive them.
Tracer: You need to be DPSing as much as possible. To remove the shield of the Eradicators, blink past and target the shield arm. Your blinking can disorient the Omnics and stun them momentarily. Be cautious of Bastions and aim for headshots as much as possible to inflict the most amount of damage.
[Lieutenant] Reinhardt, [Chief Engineer] Torbjorn, [Cadet] Tracer, [Combat Medic] Mercy
Null Sector Enemies
You fight to reclaim King’s Row from the Null Sector onmics who have taken over and are threatening human and onmic lives. To do this you need to hack into three different terminals to stop large turret guns from working. This allows Overwatch to drop an airship that will blow up a door, protecting the battle ready OR14-NS units, in the heart of the building.
Slicer, Nulltrooper, Eradicator, OR14-NS, B75-N and Detonators
