What do Zarya's Barriers do?
Particle Barrier is bound to Zarya's Ability 1 which is cn_LB by default.
Projected Barrier is bound to Zarya's Ability 2 which is cn_RB by default.Particle Barrier allows Zarya to protect herself with a barrier while Projected Barrier allows Zarya to protect an ally with a barrier. Both barriers have similar properties.
These barriers have 200 health and have a shared cooldown of 10 seconds, but have 2 charges (also shared). The barriers cleanse all status effects aside from stuns and give Zarya Energy when damaged. The only difference is that the Projected Barrier cannot be applied to the same target within 2 seconds.
How does Zarya's Energy work?
As stated before, damage dealt to Zarya's barriers give her Energy. This Energy strengthens her primary and secondary fire. Each barrier can give up to 40 Energy. Zarya losses 2.2 Energy/second. Dying will reset Zarya's Energy to 0.
How do I unlock Power Overwhelming?
To unlock this achievement, you must keep your Energy above 70 for a minute. If you manage to get to 100 Energy, you only have ~13.5 seconds until it drops below 70. Here are a few ways to gain Energy.
D.Va
- Self Destruct - Deals enough damage to give you 40 Energy and is easily countered
- Re-Mech - Deals enough damage to give you 40 Energy but requires a bit more timing and has a smaller range
