Simonson received shipments of battlecruiser-weight neosteel armor, and testing produced seismic shocks and electromagnetic discharges detectable from without. In 2503, and with no further information, Umojan agent Pandora infiltrated the facility as part of a group of visiting officials and discovered the Odin undergoing testing. The intrusion was discovered, but Pandora escaped to warn the Protectorate. The Protectorate planted information implicating the Koprulu Liberation Front.
The Raiders abandoned the walker and it was recovered by the Dominion. The Odin was later deployed to defend the Korhal Palace in Augustgrad during the Swarm invasion of Korhal and was subsequently destroyed. The palace fell and Emperor Mengsk was killed.
The Odin is designed for prolonged front line duty, with firepower capable of destroying entire cities. It is armed with two twin-linked T800 cannons, shoulder-mounted Hellfire missile pods, four 330mm howitzers, and at least one nuclear missile. The chassis is commensurately durable. The walker is well-suited to spearhead assaults on entrenched positions. The crew space includes a toilet.
"So how does the Odin rate as a fighting machine?"
"Brother... it is the single greatest creation in the history of mankind. Stridin' around dispensin' righteous fury just about brought a tear to my eye."
In "Media Blitz," the walker is controllable but lacks the nuclear missile ability, and cannot be transported by a dropship or a Hercules dropship. It damages civilian units and structures by walking over them or if a civilian car crashes into it. If destroyed, it leaves behind wreckage (with 2500 hit points, but no abilities, not even the Immortality Protocol). Findlay ejects and the mission continues, although the player is left bereft of their hero.
Unlike the regular thors, the Odin's anti-air attack does not do splash damage. However, its ground attack does do splash damage, though not over a very large area. It does not gain HP or attack rate bonuses due to Vanadium Plating or Ultra Capacitors.
The Odin appears in the final mission of the heart of the swarm campaign as a boss unit that will go after the Hyperion. The best way to destroy it is with ultralisks, hydralisks and zerglings. If the player so chose, Impalers will make quick work of it.
The Odin serves as a calldown for Tychus Findlay in Co-op Missions at level 3. The calldown will despawn Tychus and put him in the Odin, which can come down anywhere on the map with vision, dealing damage to all enemies it lands on. The Odin can use a barrage ability to deal heavy damage in an area, or at Tychus level 15 can research the Big Red Button ability, which lets the Odin launch a nuke that deals massive damage in a large area.
Calls down the Odin at the target location, dealing 150 damage on impact. The Odin takes Tychus as the pilot and revives him if he is inactive. It is controllable and will fight for 60 seconds.
Dutiful Dogwalker: The Odin no longer requires Tychus as its pilot, its duration is increased by 100%, and its cooldown is reduced by 40%.
60 120 (with Dutiful Dogwalker)
Basic: 360 (Initial cooldown=600) Mastery: -4 per Odin Cooldown mastery point. Down to a minimum 240 (Initial cooldown=600) With Dutiful Dogwalker: 216 (Initial cooldown=600) Mastery: -2.4 per Odin Cooldown mastery point. Down to a minimum 144 (Initial cooldown=600)
The Odin originally had two additional abilities: Automated Repair and EMP Burst.
Automated Repair regenerated 125 life per second for a duration of 8 seconds when activated. EMP Burst worked much in the same as the psionic shockwave ability used by the queen in the mission "Belly of the Beast", with the exception that it only stunned mechanical units (including structures).
