Underestimating the Orz Nemesis would likely be the last mistake anyone can ever make. Like its name suggests, this ship is a goddess of revenge, coming to inflict pain and vengeance on the galaxy. Never, under any circumstances, chase after the Nemesis!
The Nemesis is fairly quick, has a fair turn-rate and good acceleration. Its relatively large footprint makes dodging incoming fire difficult, although not impossible.
The Nemesis is armed with a moderately powerful howitzer cannon which is remarkable in that it can be rotated to different firing positions during combat by holding the secondary weapon button while using the turning controls. The rotational turret allows usage as a strafing weapon or as a backwards utilized attacker-repellent. The energy costs of this weapon are rather large, however, and it can only fire volleys of two or three shots at a time. Each hit from the howitzer kills three crew members.
Orz crew, encased in robotic, armored exo-skeleton, can exit the ship from the aft portholes — launched by holding the secondary button while pressing the fire button — and enter an enemy ship by burning a hole in its hull. These Orz Marines then start roaming the enemy ship’s corridors, killing any enemy crewmember they encounter. However, there is also a small risk that an Orz Marine itself will fall victim to the enemy crew and be killed. Especially useful in large groups, the Marines can blast a ship entirely by themselves. Any Marine aboard an enemy ship when it explodes will jet back out into space and set a return course for the Nemesis. The Marines are also very adept at using a Leyland Gravity Whip to speed them towards their target, a tactic for which they have been specially trained.
When the Marine boards an enemy ship, it instantly kills one crew member. Afterward, for every marine aboard an enemy ship, every half second, a random decision is made. Half of the time, an enemy crew member will be killed and the Marine survives, 7 out of 16 times, the Marine survives without inflicting any damage, and 1 out of 16 times the marine dies without doing any further damage. On average, a Marine can kill nine crew members before dying.
A very effective ship that rarely fails, although prolonged combat against multiple opponents can take a heavy toll.
