What does Barrier Field do?
Barrier Field is bound to Reinhardt's Secondary Fire which is by default.Reinhardt projects a 1200 health barrier in front of him. His allies are able to shoot through the barrier, but it will absorb 99% of enemy fire. When the barrier is dropped, it will start recharging after 2 seconds with 144 health per second. Recharge will stop if barrier is activated.
The 1% Barrier Field cannot block is Winston's Tesla Cannon, Symmetra's Energy Ball, Moira's Coalescence, and melee attacks, but they will still damage the barrier.
How do I unlock I Am Your Shield?
You must block 7500 damage and you must not die. If you die the damage blocked will be reset. This can (and must) be done with multiple barriers as a full barrier has 1200 hitpoints.
Any damage dealt to the barrier will count towards the achievement, but what are the best ways to block damage?
Chokes
Putting your barrier up in a choke point will cause problems for the enemy team and they will try to destroy it. The best choke points are usually on Hybrid maps which tend to have paths that lead straight towards the first point (as opposed to a flank).
Ultimates
Blocking ultimates is a risk-reward system because some ultimates, such as Pharah's Barrage and Roadhog's Whole Hog, are able to destroy your barrier in seconds and kill you, but a destroyed barrier means you blocked 1200 damage. Some ultimates, such as Soldier: 76's Tactical Visor, will deal some major damage, but will usually not be able to fully destroy a full barrier alone.
Payload
By standing in front of a payload, the barrier are a nuisance to the enemy team and will be top priority. If you are attacking, the payload will also be able to heal small amounts of damage.
