Tyhrranosis is a planet in the Solana Galaxy featured in Up Your Arsenal. It is the desert homeworld of the tyhrranoids, who have established a large fortress at Korgon Base, the lair of the Momma Tyhrranoid, and a remote military outpost on Kavu Island.
Ratchet and Clank spearheaded an invasion of the planet with the Galactic Rangers. The group launched an assault on Korgon Base, beginning with the destruction of its power generators. With the help of Skrunch in a turboslider, Ratchet then destroyed several plasma cannon turrets before confronting and defeating the Momma Tyhrranoid. Following this victory, the duo traveled to Kavu Island to lead another Ranger assault on a secondary tyhrranoid base.
History[]
Qwark's plan of attack.
After the successful infiltration of Dr. Nefarious's base on Aquatos, Captain Qwark drew up a plan to attack Tyhrranosis. His plan once again placed Ratchet and Clank on the front lines, while Qwark and the rest of the Q-Force were scheduled to be at the lunch buffet on the Starship Phoenix.[2]
Sasha sends a turboslider.
In "Take out the power generators", Ratchet performed a HALO jump with other Galactic Rangers onto Korgon Base. He and the surviving Rangers destroyed a power generator, disabling the base's mortar launchers and allowing the main Ranger dropship force to land. Sasha Phyronix then deployed a turboslider, with Skrunch manning the cannons, for the next mission, "Destroy the plasma cannon turrets".
Qwark claims credit.
After destroying the turrets, Ratchet and Clank fought and killed the Momma Tyhrranoid in her lair. Immediately after her defeat, Captain Qwark swooped in to take credit for the kill in front of Darla Gratch for a news report.
Later, in "Destroy the Encampment", Ratchet led Operation: ISLAND STRIKE, a Ranger assault on the remote tyhrranoid military base on Kavu Island. After defending the Ranger base from waves of tyhrranoids, Ratchet used a captured hovership to repel an attack by tyhrranoid dropships. While the Rangers devised a plan to disable the forcefield protecting the enemy base, a Ranger named H-26 sacrificed his life to bring it down.[3] Ratchet then led the final charge, destroying the tyhrranoid base and completing the operation.
Geography[]
Tyhrranosis is a desert planet with a harsh climate and a distinct yellow atmosphere, which gives its bodies of water a dark red color. The environment is mostly barren, dominated by large, flat-topped mountains and sparse vegetation consisting of small red plants and tall, hollow flora. The major tyhrranoid installations are located on remote islands.
Korgon Base[]
The central area of Korgon Base.
Korgon Base is the main tyhrranoid fortress and the location of the Momma Tyhrranoid's lair. The base is built on a remote island and defended by mortar launchers and plasma cannon turrets. The architecture is distinctly insectoid, with buildings supported by leg-like structures.
The central area of Korgon Base is a large, hilly, open region dotted with tyhrranoid watchtowers. Roads connect the landing zone to the rest of the base, leading towards the various plasma cannon emplacements. A large mountain on the western side contains a cavern filled with slime pits, which must be navigated to reach the plasma cannon turret perched on top. Other turrets are located to the northeast and southeast, with their power generators housed in smaller, nearby structures.
The Momma Tyhrranoid lair is a towering, orange building on the northern end of Korgon Base. An elevator leads to the main control room, a vast chamber composed of bridges over a slime pit. The Momma Tyhrranoid uses the webbed ceiling to crawl around during the battle.
Kavu Island[]
Kavu Island.
Map layout of Kavu Island.
Kavu Island is a remote military base visited in "Operation: ISLAND STRIKE". The bulk of the island is a large mountain, with tyhrranoid tower structures built into its caves and on its peaks. The main combat area is a symmetrical layout on the northern side of the island, consisting of three chunks of land connected by bridges.
The Rangers' blue base is located on the western chunk, while the tyhrranoid red base is on the eastern side. The middle area contains two plateaus; one near a hill on the northern edge, and another that features a hovership pad and a large, inaccessible entrance to the tyhrranoid structures inside the island's mountain.
Multiplayer[]
Map layout of Korgon Outpost.
The multiplayer map Korgon Outpost is based on Kavu Island and supports Siege, Capture the Flag, and Deathmatch modes. The map features an almost identical mirrored layout to its campaign counterpart, with the key exception of an additional central building between the two bases.
The bridges connecting the bases to the rest of the map are initially closed. The southern bridges can be opened via bolt cranks, granting access to a turboslider and the southern nodes, which in turn provide a hovership. The northern bridges can only be opened from the far side, but a pair of versa-targets allows players to Swingshot across the gap, creating a strategic bottleneck.
The central building's interior features a series of disconnected ramps navigable by turboslider and walls that can be scaled with Gravity Boots. The central node controls the position of these ramps; when captured, it reorients them to allow a team's turbosliders to drive directly from their base to the other side. This area also contains the Holoshield Glove.
The northern section of the map contains two more nodes, each granting another turboslider and access to the Mine Glove and Minirocket Tube. These nodes flank a central hill which provides a good vantage point. Opposite these nodes are climbable platforms that serve as sniper nests, each holding a Flux Rifle.
Behind the scenes[]
The turboslider was originally developed for a racing segment on Florana that was ultimately scrapped. As the vehicle was already complete, it was reused on Tyhrranosis, which had been designed to accommodate non-linear gameplay.[4]
The Momma Tyhrranoid boss battle was designed by Brian Allgeier and programmed by Jerrod Putman, for whom it was a first major task. The design, which took inspiration from The Legend of Zelda, went through at least three iterations. Putman programmed the boss's cinematic scenes entirely with code from her perspective, despite not being an animator.[5]
The 'noid missile stations on Kavu Island won an internal Snowbeast Award for receiving strongly negative reactions from playtesters. The missiles were difficult to avoid due to unclear targeting and little warning. Despite pleas from other developers to change them, the programmer reportedly resisted the requests.[6]
