This is the Brick Armour "ultimate" power-up in Wreckout.
Ultimates can be activated when your Skill Meter fills up by... well, playing skilfully! You can activate it when the Skill Meter reaches level one, or wait until level 2 or even level 3 to increase the effect of the ultimate.
We've got a handful of ultimates working in the game, but we want a whole bunch more and we'd love to hear your ideas!
