Reinhardt's shield ability creates a shield impenetrable for enemies and their weapons until 2000 damage has been dealt to it.
Is it possible for allied players to take cover behind the shield and shoot through the shield from the "inside"?
In case it blocks projectiles from both enemies and allies, do allies damage the shield?
Best Answer
Allied projectiles will go through Reinhardt's shield without difficulty. There is no friendly fire in Overwatch, but your own splash damage abilities can hurt yourself (Junkrat and Pharah most notably).
Also note that there are a couple of enemy projectiles that penetrate his shield, see this question for a complete list: Does Reinhardt's shield block all abilities?
The actual players can also pass through the shield without difficulty, both enemies and allies.
