Holographic Armor?

Technically it's not holographic armour; the hologram is simply an indicator to nearby teammates (and enemies) that it's active and not to get too close, because it's volatile and dangerous. From the codex:

"Tech Armor" is the common term for a complex series of field generators that disrupt incoming force using a stationary warp effect. The theory is that bullets that would normally shatter on impact instead break apart when they strike the field. The field then bleeds away the shrapnel's kinetic energy. The standard design for tech armor traps the warp field between two low-yield kinetic barriers to protect the user from the field itself. When the outer barrier fails, the warp effect is discharged, potentially harming anyone nearby. For this reason, many soldiers modify the armor with a haptic-style light effect to warn allies not to get too close. On missions where stealth is paramount, this effect is disabled. Cynical soldiers joke that the design is called "tech armor" because if it were simply called "warp armor," no one would use it.

Personally, I think warp armour sounds awesome, though So it's actually a combination of tech and biotics, hence why it's a Sentinel ability.


Anyway, yes, it's going to be in ME:A, presumably in MP as well since it's a staple Sentinel power. Here's a turian using it in the gameplay video:

yes, enemies have it, but what about the playable characters in the MP?
nice info, thanks
