Skagzilla

Skagzilla is an optional boss in the Dahl Headlands. He is a massive Skag, about 3 1/2 times the size of an Alpha Skag, and far more difficult to kill. He is encountered in the mission Big Game Hunter.

General Strategy
Skagzilla will roar when he first emerges into the arena, providing an opportunity for players to score multiple critical hits before the fight actually begins.

It should be noted that since he is infact a skag, he has a high resistance to Shock and Incendiary damage. However, Explosive weapons can still deal considerable damage to Skagzilla on critical hits.

Skagzilla has several different attacks. The simplest of these is to close the distance from his target and slash with his claws. This attack can be avoided simply by backing away. This attack exposes his unarmored belly. He will do this if his target is within close range.

Like his lesser brethren, he will also put his head down and charge. This attack is difficult to avoid and causes knockback. When his head lowers to charge, the rush can be avoided by turning away and sprinting in a path perpendicular to Skagzilla's direction of travel.

Another of his attacks is a pounce and body slam with accompanying shockwaves radiating through the ground. This can be avoided by sprinting opposite the direction he is pouncing, slightly to the side when he leaps, and then jumping just before he hits the ground. Again, this exposes his unarmored belly and flanks.

He will also unleash a beam of energy which he will sweep from his right to left. This attack exposes his mouth granting the player several seconds of non-stop criticals, however being caught in the beam is very damaging, knocking the victim back in the process. The beam itself has deceptively short range, so when Skagzilla rears his head to fire a beam, it can be avoided by sprinting out of range. A second method is to avoid the beam entirely by dashing forward to his immediate vicinity when prepares for the beam attack. Multiple shots to the head when he is stalking forward coaxes Skagzilla to use his beam attack.

His last attack is a massive ball of energy that deals splash damage and does increased damage if caught at point if impact. This does not present a significant opening for an attack, as Skagzilla's mouth is open for less than a second during delivery, and presents little opportunity to get in at his sides before he is moving or attacking again. There is little warning of this attack being prepared, so focus on creating distance from Skagzilla. Take note Skagzilla will attempt to lead the shot.

Glitches

 * It is possible to get a Runner into Skagzilla's enclosure by carefully driving up and around rocky ledges near the race track. Skagzilla will, like many other enemies, die almost instantly if hit by a Runner.
 * There is also a way to get him to jump out of his enclosure by standing on the rock ledges near the pen, allowing him to run free across the Dahl Headlands. (Watch out for Runner Patrols, as the vehicle will kill him instantly if he is hit.)

Trivia

 * Skagzilla is obviously a play on words of the poster monster, Godzilla. This is further emphasized by his beam attack, reminiscent of Godzilla's own atomic mouth blast. This also hints toward Mothrakk which is a play on words to Mothra, another Godzilla monster.
