Krogan Berserker

Krogan Berserkers are tank bred krogan created by Warlord Okeer, they were bred in an attempt to create the perfect krogan. While in their tanks, these krogan were shown images such as the vulnerable parts of alien anatomy and how best to take advantage of them, as well as past battles in an attempt to both prepare them for war and inspire hatred for Okeer's enemies.

The failed specimens were given to Blue Suns commander Jedore for her army, and Okeer kept the one specimen he considered perfect for himself. However the Berserkers proved to be extremely violent with their main desire being to fight and kill, rendering them uncontrollable. They mature very quickly as one encountered by Shepard was only 7 days old and fighting several Blue Sun mercenaries. Berserkers seem to be susceptible to blood rage making them even harder to control.

Capabilities
Offensive

Encountered on Korlus, Berserkers are are one of the most ferocious opponents in close quarters due to their shotguns and access to the Carnage ability. They are constantly advancing and unless they're put down, they will enter close quarters and use their charge ability which can be fatal.

Defensive

The Krogan Berserkers have good armour and very good health regeneration. They are able to take large amounts of damage.

Tactics
Incinerate and Inferno ammo will make taking them out considerably easier, stripping their armour away, and stopping their regenerative capacity.

Trivia

 * The blood rage that causes the berserkers to berserk is also very similar in nature to the bärsärkar-gång fits the norse berserkers underwent.
