"Power assisted suit allows for faster movement than normal while still providing excellent body armour protection."
The Rubicon Power Assist is a vest made by Rubicon Industries in SAS: Zombie Assault 4 which features the highest movement modifier of any armor piece unaugmented, and also grants a boost to revive speed. Because of its high movement modifier, slight revive speed increase, and overall utility, it is widely used mid-game and late-game (as the or version), especially in speed-based builds.
Unfortunately, the Power Assist has pitiful defense; it is the fifth weakest piece of armor in the game, with only the non-vest HVM Kevlar pieces having inferior defense, contrary to what the description says.
If used with Assault, it is recommended to mix with Dragon Fly armor parts (which provide movements & good chemical resistance) so that players can unleash true potential of Assault class (Firepower & Mobility).
At one point the revive bonus was removed, but was later added back on Feb 20th, 2015 due to the removal of the bonus being a bug.
The Rubicon Power Assist's appearance in the mobile port of SAS 4 is based off of the PC's original appearance.
