Unlock Cat Invasion Classes

Cat Invasion advertises classes with unique abilities, but this wiki only documents three named ones: Medic, Ninja, and Alchemist. If a loading screen or shop row shows more silhouettes, wait for a page that can name them. Do not invent a fourth class and then spend Gold on a guess. Pair this guide with the tier list and the players hub before you commit an unlock to a long invasion.

Classes are lobby/meta choices. They do not replace the coin order in Getting Started or the range dump on the wave 100 guide. A Medic who never pauses still loses the wooden base. A Ninja with no armor still eats Floppa lasers. Unlock the class, then still buy snowballs, coin boosts, and the 3,000-coin armor at wave 50.

Alchemist: day 7 of dailies

Alchemist is the clean unlock. Show up for daily rewards seven days in a row. That is the whole instruction. The daily chain is also why Gold Farming tells you not to vanish into the AFK zone for a week and forget the lobby. Missing a day delays the class. There is no documented shortcut on this page, and we will not invent a Robux skip that the shop has not priced in a source we trust.

Once Alchemist is owned, it is an account class you can select in the lobby. It is not an in-run potion. Do not expect the pause shop to “buy Alchemist” with coins. Coins still buy weapons, armor, walls, builders, turrets, food, and merchant potions. Alchemist sits next to Medic and Ninja on the class rack.

If you are brand new, start the daily chain on the same session you redeem 19MVISITS and 900KMEMBERS. That way the seven-day wait is already running while you learn pause shopping. The codes hub is the live list; class unlocks are not hidden inside those strings.

Medic and Ninja: grind unlocks

Medic and Ninja are grind unlocks. Play the game. Clear waves. Come back. This wiki does not publish a fake kill count, wave gate, or Gold sticker price for either class. If a video overlay flashes a number we cannot verify, we leave it off the page.

What we do know is the job. Medic revives teammates. That is the group class. Cat Invasion is online co-op: solo or a server of up to 18. A Medic in a coordinated lobby turns a laser down into a second try. A Medic in a chaotic 18-player server that never pauses is still watching the wood fall over. Unlock Medic because you actually group, not because revive sounds nice on a solo AFK tick.

Ninja is the other grind name. Select it when you have it; do not pretend it is a Floppa skip. Range, armor, and damage potions still do the named-cat damage. If you want relative value, that comparison belongs on the tier list and the players hub, not in a paragraph that invents hidden Ninja stats.

Grind time is cheaper if the underlying run is correct. Follow melee-to-200-then-range so you see wave 50. Beat Floppa so the session is long enough to count. Use Gold Farming so codes and Golden Weekend feed the account while the daily chain and the grind both run. Dying at wave 20 in a pillow does not grind classes faster. It just restarts the lobby.

How to spend (and not spend) around classes

Gold is the meta currency that classes care about. Coins are not. Do not dump an in-run wallet into the lobby hoping a class appears. Do not skip merchant coin boosts because you are “saving for Medic.” Those are different purses. Redeem codes first, play Golden Weekend when it is up, treat the Double Gold pass as optional, and treat the AFK zone as a slow background tap. None of that is a class unlock by itself except the daily chain for Alchemist.

Plasma Armor at 79 Robux is an armor gamepass, not a class. It will not revive a teammate. It will not complete day 7. Buy it only if you want the armor shortcut described in How to Play.

Group etiquette matters once Medic exists. Say you can revive. Ask the lobby to pause. If nobody pauses, you are a Medic in a coin drought. Leave and find a quieter server, or go solo until the wave 100 route is automatic. Servers still cap at 18; that cap is not a promise of 17 competent teammates.

Which class to chase next

If your daily chain is not finished, chase Alchemist. It is the only unlock with a calendar. If you already group and people keep going down to lasers, grind Medic. If you mainly solo, Ninja can wait until the grind happens naturally on the way to badges. Do not park your account in the AFK zone for a week to “main Ninja” while Floppa is still unbeaten. Named cats and wave badges (25 through 100, then 125, 150, and the later stamps) are better proof you are ready for a class than a lobby screenshot.

When the unlock pops, take it to the tier list and the players hub before you rebuild your whole identity around it. Then go back to the invasion with the same shop: range first, coin boosts on sight, expensive armor at 50, damage potions for Floppa. Classes change how a body in the lobby behaves. They do not rewrite the meme-cat spawn table. If a later patch names another class, it will get its own section. Until then, the list is three: Alchemist on day 7, Medic and Ninja on the grind.
