"If it is in your way, tenno - flatten it until it ceases to be so."
Rhino is the heaviest warframe, combining both offensive and defensive capabilities.
Rhino Charge - charges towards a target, clobbering any in his path and goring his victim
Iron Skin - hardens his skin, insulating himself from all damage
Roar - grants all nearby warframes increased damage for a short duration
Rhino Stomp - stomps with a force sufficient to disrupt time, tumbling enemies around him in stasis
Emit a shockwave after landing from a great height
FEELING WHILE PLAYING: Rhino's second skill, Iron Skin, really holds up well in missions that aren't too far above his current level. It can be kept active all the time as it doesn't have a duration, basically acting as ablative armor. Once its been chipped off, simply reestablish it and keep going. His fourth skill, Stomp, is ludicrously funny as it thrusts people in to the air and holds them there for easy shooting which is great if your aim isn't the best or if you've been swarmed. Roar seems good on teams although Stomp would probably be a better option once you can pack on some efficient mods to keep energy up.
Overall he feels very strong and tanky and quite forgiving of mistakes.

Broke down, got some platinum and immediately splurged on the Palatine skin for Rhino. I do not regret it.
