This is my analysis of Arena 1 and the following arenas are detailed in other solutions
Wave1 = Orks and Guard
Wave 2 = Orks and Guard
Wave 3 = Orks and Guard
Wave 4 = Guard & Capture point on the ridge next to the door
Wave 5 =Orks, Guard, and 4 Space Marines
[I do not use plasma or melta weapons so they will not be detailed]
Orks are all familiar:
Gretchin - a ground pound , 1 melee swing or 2 rounds from any bolt weapon with down these little cretins.
Ork Boys - 3 shots from any bolt weapon, 1 swing for the maul and 2-3 for swords will kill the mainstay of the Ork horde.
Ork Berserkers - 2 swings from a maul (1 direct hit with killing blow), 3-4 with swords and around 15-18 bolt rounds (less if using heavy bolter) will put down these suicide orks.
Shootas - 1 hit with the maul, 2-3 with a sword or 3 shots from a bolt weapon with drop these ranged xenos.
The Guardsmen are all new units:
Guardsmen - These little humans are easy to kill. 1 hit with the maul, 2 with the swords and 4 in the chest or 3 in the head with a bolt weapon.
Stormtroopers - Come in two variants upon close examination of the guns. Melta guns and granade launchers, both take the same hits as the standard guardsman.
Chainsword guardsman - In small groups, these human can do damage to both armor and health. Same hits as melee but 6-7 shots for bolt weapons.
Sanctioned Pyskers - These are the staff weilders that fire the lightning. The have a quick stun melee attack and the lightning. Melee does little damage to armor while the lightning drains it and can do good damage if left unchecked. 3 hits with the maul (1 direct hit with Killing blow), 5-7 with the swords and bolt weapons hit a shield so unknown number of bullets needed.
Space Marines - The lapdogs of the false emperor. They come in several variants which i will explain in other solutions as they show up. 4 of the bolter variant show up in arena 1 during wave 5. At range, they can do good damage to both armor and health but in close combat, they have a slow swing with a power axe much like with the campign chaos marines. They have armor like you but it takes less punishment. 2-3 swings with the maul and 7-9 with swords, bolt shells need to break the armor so roughly a clip and a half to kill for a bolter (Kraken rounds) and anywhere between 35-45 for a heavy bolter.
This concludes my breakdown of the enemies of Chaos for arena 1. The Xenos and Imperial lapdogs fear you. Press your advantage.
DEATH TO THE FALSE EMPEROR!!!
