Cat Invasion Auto Upgrade Scripts

Auto upgrade scripts watch your coin count and buy the next tier the moment the price is affordable. Community GUIs for Cat Invasion usually expose separate toggles for ranged, melee, armor, wall, and food, plus an auto repair or auto-wall switch. That sounds like a gift until the script buys melee you already outgrew, skips the merchant coin boost, and leaves you under-armored at wave 50.

This page explains those toggles. It does not give you a loader URL, a key, or a payload. Auto upgrade still needs a third-party executor. That can ban the account. Pair this with auto farm scripts only if you already accept that risk. The scripts hub has the generic loadstring(game:HttpGet("URL"))() placeholder and the keyless versus key-system warning.

What each upgrade toggle usually buys

Cat Invasion splits wallets on purpose. Coins are in-run. Gold is meta. Auto upgrade spends coins. It does not redeem codes and it does not buy classes with Gold. If a menu claims it will auto-buy a class, treat that as a different, even riskier hook.

Typical coin toggles:

• Auto Upgrade Ranged — walks the snowball/gun tree. This is the toggle that matches the human plan on the upgrade planner. If you use only one spend switch, this is the one people mean.
• Auto Upgrade Melee — keeps buying the close-range weapon. Fine for the first ~200 coins, then it becomes a trap. Tutorials tell you to stop melee there and swap to range. A script that never stops melee will starve range, armor, and walls.
• Auto Upgrade Armor — buys armor tiers as coins allow. Human players often wait for the 3000 armor purchase around the wave 50 Floppa check. A greedy armor toggle can buy small armor too early and miss the 3000 breakpoint, or buy 3000 so late that Floppa already landed.
• Auto Upgrade Wall / builders — puts coins into walls and builder speed. Necessary when wood starts failing, wasteful if you buy it while cats still die in the spawn kill zone.
• Auto Upgrade Food — restocks or upgrades food. Combined with auto food on a farm GUI, this can drain coins into snacks you will not need if the aura is already deleting waves.
• Auto Repair / auto wall — spends to repair damage instead of (or in addition to) upgrading the wall tier. Useful in co-op if nobody is looking at the wood. Useless if the script repairs a wall the pack has already walked through.

Some menus add a priority list or a “buy cheapest” mode. Cheapest-first is how you end up with maxed melee and a starter snowball. If the GUI cannot pin range first, it is not following the planner. You are better off pausing the wave and clicking the upgrade yourself.

Why a script is worse than a pause

Cat Invasion lets you pause a wave to spend. That is the intended auto-upgrade: you stop the cats, open the shop, buy range, buy the merchant coin boost if it is on sale, then resume. A loader that buys in real time can:

• Spend coins the frame they drop, before you see a merchant coin boost.
• Upgrade melee because it is the lowest price on the board.
• Skip walls until the base is already leaking.
• Fight you for the same coin pile if auto farm is also running and auto food is eating the stack.

Human order from current tutorials:

1. Melee only until about 200 coins.
2. Pause and buy snowball / range.
3. Buy a merchant coin boost when it appears.
4. Keep upgrading range (250, then 550, and onward).
5. Around wave 50, buy 3000 armor for Floppa.
6. Add walls / builders when the wood actually needs it.

A script that cannot express that sequence will play a different game than the one you planned. If you still inject, disable melee upgrade after the first swap, disable food upgrade unless you are dying, and leave range plus a manual armor click at 50. That is already more babysitting than pausing.

Gold, classes, and gamepasses

Auto upgrade will not save you from a bad Gold spend. Redeem working codes first (19MVISITS and 900KMEMBERS, 250 Gold each). Then buy a class you will play. Dumping Gold into a weak class is covered on the class tier list. Scripts that promise auto class unlocks are asking to touch meta currency; that is a larger theft surface than a coin toggle.

Gamepasses — Plasma Armor at 79 Robux, Double Coins at 119, VIP at 149, Double Gold at 149, +3 Turret Limit at 119 — are Roblox purchases. No community GUI should be trusted to buy them for you. Double Coins and Double Gold also change how fast a script can dump a wallet. Faster income plus a dumb melee toggle is a faster stall.

Risks

Same rules hit as every other executor page on this wiki:

• Roblox can warn, lock, or ban the account.
• The loader URL can serve malware.
• Key pages add extra places to phish the session.
• A crash mid-upgrade can leave you with a half-bought tree and a dead base.

This wiki does not host scripts, does not rate them, and does not call auto upgrade undetected. OneBed Studio’s Cat Invasion page and group are the official surfaces. Pause-to-upgrade is the official spend tool.

Follow the planner by hand if you care about coin order. A script that dumps coins into melee will stall you before Floppa.
