Ninja Trooper

Perkins: Sir, I got beat up by ninjas!

Morgan: ....PWAHAHAHAHAHAHAHAHAHAHAHAHA, NINJAS.

Description
A clan of Ninjas has tracked down your Outpost. Their sudden arrival was quite alarming, as they initially attacked! Their mission wasn’t entirely clear; they seemed to be looking for something or someone… As usual, Perkins was the wrong place at the wrong time and suffered some minor, but mostly severe injuries. Don’t worry, the kid should be ok.

Ramsey worked his magic, and was able to persuade these Ninjas (ahem… pay them off) to call off their attacks. They were so persuaded in fact, that they’ve decided to stick around to join the army and fight for you!

These warriors are specialized in infiltration, sabotage, assassination, espionage, and open combat. They’re masters in the art of war, so be sure to get to your Barracks asap! The Ninjas plan to leave the Outpost on August 20th and will no longer be trainable. Get them while you can!

Overview
Special promotional period: Aug 17-20, 2012.

The Ninja Trooper is available only for a limited time, for players of Level 35+ and in a Barracks. Similar to the Tamed Sandworm, the Ninja Trooper starts with three different attacks, but only 2 ability slots - so the player will have to decide which two of the three to equip.

The starting attacks include a wide-area ranged attack with shurikens, a "strike anywhere" sword attack that can only target Soldiers, and lastly a smoke bomb attack that stuns a single target.

Two additional attacks can be researched at ranks 2 and 3 respectively. The first is a damaging bomb attack that has shorter range compared to a Grenadier or Boom Boom (range 1-2), but with a bit of armor piercing properties. The last attack is available at rank 3 and is effectively the vehicle-only version of the primary katana attack, except it has armor piercing properties AND a guaranteed stun effect.

However, the two attacks both cost nanopods which means extra nanopods spent on an already expensive unit. It also only has 3 total ability slots and 5 attacks so that causes a tough choice on what attacks to keep or use in battle.
