Ototo Development Team

Ototo Development Team (also known as Ototo Corps) is a feature introduced in the version 6.0 update. The feature allows the player to develop a new appearance for the Cat Base, Cat Cannon attacks and also further increase the Cannon's power. Ototo Development Team can be accessed by scrolling to the right in the GAMATOTO screen.

Explanation

The feature is unlocked after clearing Empire of Cats Chapter 1 and is only functional after the player has upgraded the Cat Cannon Power, Range and Charge to level 10 at the Upgrade Menu. To develop, Ototo requires some resource materials and workers to build.

The materials can be obtained randomly when clearing stages in Stories of Legend or Uncanny Legends. The material type dropped usually has a tendency with the stage cleared, eg: Stages with Zombies usually drop Beast Bones; stages with Red Enemies usually drop Bricks. Materials can also be obtained from Heavenly Tower, Legend Quest, Baron Seal Strikes, Le'Grim Strikes, or the Builder's Blitz Stages.

The engineer(s) required can be obtained from Gamatoto Expedition randomly after clearing an expedition, one at a time with a maximum of having five engineers.

Note that when in progress of upgrading, you may still obtain engineers from Gamatoto Expeditions.

Obtaining materials

Materials are scattered throughout Stories of Legend and Uncanny Legends. Upon clearing any stage, there is a chance to get materials. There are types of material: Bricks, Feathers, Coal, Sprockets, Gold, Meteorite, Beast Bones, and Ammonite, each associated with a certain enemy type (Red, Floating, Black, Metal, Angel, Alien, Zombie, and Relic respectively). The type of materials dropped is not directly affected by enemies in that level; for example, Feathers can be received in levels that don't spawn any Floating enemies at all. Materials won't drop in most Event Stages (Red) and Collaboration Stages (Purple). No levels have a limit of how many materials you can obtain or how many times they will drop, so the player could just grind one stage forever. Torture Room is an effective stage for this since it's so quick, and every material drops there except Meteorite and Ammonite.

The drop rate is applied on all stages in a sub-chapter, so it's always more efficient to farm a stage with the lowest energy cost. The star difficulty only affects how many items you can farm per a stage clear. Also, some players may not be at the later sub-chapters. This is why some of the below recommendations for material farming contain lower percentages.

• 1-Star gives a maximum of 3 items.
• 2-Star gives a maximum of 4 items.
• 3-Star and 4-Star give a maximum of 5 items.

The best sub-chapters to gain each material:

• Bricks - Glucosamine Desert (27%)
• Feathers - Risqué Terrain (16%), Laboratory of Relics (22%)
• Coal - Squishy Cave (20%), Capone's Jail (24%)
• Sprockets - The Legend Begins (13%), Quarantine Isles (15%)
• Gold - Grotesque Gallery (15%), Pararila Peninsula (17%)
• Meteorite - Scars of War (12%), Area 22 (33%)
• Beast Bones - Walk of Fame (32%)
• Ammonite - Drunken Foundry (35%)

Drop rates for materials per sub-chapter have a trend of matching the traits of enemies found in its stages. For example, Area 22 has a high drop rate for Meteorites and Suburbs of the Dead has a high drop rate for Beast Bones, as both sub-chapters feature a heavy presence of Alien and Zombie enemies, respectively.

Getting Engineers

Engineers can be obtained from Gamatoto expeditions. Player will be notified if obtaining one. Can be obtained at the same time as an expedition assistant for Gamatoto. Retiring an expedition assistant also gives the option to change them to an engineer.

The engineer will be spent on base upgrade, and players can have up to 5 at once. Once the limit is reached, no extra engineers can be obtained. Advanced base upgrades can require up to 4 engineers.

Upgrading tutorial

To access Ototo Corps, simply go to the Gamatoto screen and swipe left. This will take you to the Ototo Corps screen. Once on the Ototo Corps screen, tap on the engineer, and select an upgrade. If the required materials are available, development on a project can commence and will finish in 12 or 24 hours.

Attacks by firing a laser beam into the ground which after a slight delay explodes into Shockwaves. Enemies in range will be knocked back and take low damage. Upgrades increase base health up to a maximum of 76,000 in addition to existing Base Health. The Cat Cannon's damage is unaffected, but Sniper the Cat's becomes 380 points stronger as its attack power is 0.5% of the base's maximum health.

Spawns a static unit called the Iron Wall Cat 100 range in front of the nearest enemy (minimum of about 150 range from enemy base). The shield has 5 health, is considered Metal, and is immune to all status effects. However, it will expire after 60 frames 2 seconds even if enemies do not deplete its health. In addition, as it considered a Cat Unit, it cannot be deployed if the maximum number of deployed units has been reached, and Zombies can burrow underneath it.

Fires waves of divine light that burst from the ground in sequence toward the enemy base. Deals damage to Zombies equal to 0.5% of their maximum health (increased to 10% if the Zombie is burrowed), forces burrowed Zombies to resurface, knocks them back, freezes them for 30 frames 1 second, and permanently kills them if it deals a fatal blow. However, it has no effect against other enemies. Upgrades increase normal percentage damage, burrowed percentage damage, and freeze duration against Zombies up to a maximum of 10%, 30%, and 59 frames 1.97 seconds respectively.

Fires an orange laser beam from the Cat Base to the enemy base. It curses all enemies in it's range for a certain amount of time.

Warning: Canceling the progress will not return engineers or materials used. Progress can be sped up using Catamins, just like the Gamatoto expedition.

Tips

• The Foundation and Style parts are purely decorative. Only the Cannon part changes the effect of your base.
• Foundation/Style/Cannon combinations are saved between formation slots, so double check which Cannon you have equipped if you're making significant changes to a formation.
• For most stages, the normal Cat Cannon is perfectly capable if not the best choice. It excels at clearing out enemies with very low health (including the dreaded Assassin Bear but not Metals), knocks enemies back, and can be used to interrupt an enemy just before they finish a long attack animation, giving the player a bit more time to attack them.
• The Slow Beam excels at applying a moderate length slow effect to all enemies on the battlefield. It is perfect for keeping fast and powerful enemies from plowing through your defenses, either after your front line is cleared by an enemy attack, or as a means of giving your status effect-inflicting Cat Units more time to do their job.
• The Iron Wall can be used to instantaneously block non-Zombie enemies from advancing for a brief moment, and is most effective against enemies with slower attack rates that do not inflict Critical Hits. Unlike the Slow Beam, the Iron Wall can result in enemies grouping up in front of the wall, which could be a good chance to wipe them out all at once with a powerful Area Attack.
• The Thunderbolt can be used to freeze all enemies in front of the furthest away Cat Unit (closest to the enemy's base) for a moderate duration, in addition to doing slight damage which may be sufficient for wiping out peons. This can delay the action of enemies that have long attack animations without knocking them back, which might be preferable depending on enemy composition.
• The Waterblast can be used to remove a significant percentage of Metal enemies' health in front of the furthest away Cat Unit. As the Waterblast removes health based the target's remaining health and not their maximum health, it is best used against Metals with the largest health pools as early as possible for maximum effect. Never use Waterblast against non-Metal enemies; it will only do 1 damage.
• The Holy Blast is an extremely potent anti-Zombie shockwave that removes a percentage of maximum health from all Zombies on the field, in addition to freezing them briefly, knocking them back, forcing burrowed Zombies to the surface (plus dealing significantly increased damage), and permanently killing Zombies who are finished off by the cannon. It is best used to intercept powerful Zombies who have already burrowed into the ground, or to chip away at and potentially finish off Zombies on the surface. Never use Holy Blast against non-Zombie enemies; it will do nothing at all.
• The Breakerblast is a fast-acting shot that quickly knocks back and breaks the Barrier of the nearest enemies. It can be used as a alternative to the Cat Cannon for knocking back and damaging only the enemies in the front, which may be preferable to knocking back all enemies depending on enemy composition. It can also be used to interrupt enemy attacks, and is easier to time due to its more immediate effect. Finally, it is very effective at breaking Barriers in a group of enemies, or one of a single tough enemy that easily obtainable Barrier Breakers might struggle with.
• The Curseblast is a curse-type slow beam, which curses enemies, but doesn't attack, so don't use it in any EoC levels because there are no special abilities in the whole chapter. Use it in ItF with certain stages, particularly excels at Moon, because there are so many aliens with special abilities.

Trivia

• Prior to version 6.8, all Cannons were capped at level 10.
• Prior to version 9.8, all Cannons were capped at level 20.
• The Iron Wall Cat is the slowest Cat Unit in the game, with a movement speed of 0.
  • It is also the only Cat Unit that does not attack.
