Cat Invaders Auto Upgrade

Auto upgrade is the Cat Invaders script for people who can aim but hate the pause menu. Instead of AFK combat, you keep moving while a GUI spends Gold on ranged, melee, food, armor, and walls. Pair it with auto farm if you also want aura. Read the scripts hub disclaimer first.

A good auto upgrade is just upgrade priority with fewer clicks. A bad one is a melee skin collector. Watch the first three purchases.

Feature list (as advertised)

Public combat/shop hubs in this game usually expose:

• Auto shoot / auto heal
• Auto upgrade ranged
• Auto upgrade melee
• Auto upgrade food
• Auto upgrade armor
• Auto upgrade wall
• Auto collect Gold bars, hearts, and fish
• Sometimes a key gate before the GUI opens

Turn ranged and food on. Leave melee off after the bootstrap. Leave wall off until your splash actually clears a pack. Armor on as you approach the Floppa wave in beat Floppa.

Cat Invaders auto farm and auto upgrade script

Paste block

Second circulating loader (SoftKillz-style hub: aura, auto upgrade wall/armor, loot, teleport):

loadstring(game:HttpGet("https://api.junkie-development.de/api/v1/luascripts/public/10fc7200dd134ce3cca42f3a031db69bbf16a90e5f144e4db6e7cab31b3ab1c3/download"))()

Some mirrors add a key system before this line runs. If the key site asks for a Roblox password, stop. If the HttpGet fails, the host moved — do not install a “fixer” executable.

Shop order the GUI should copy

1. Melee only until ~200 Gold (or skip if codes already dumped 500 into the pocket from the codes hub).
2. Ranged ranks: 250, 550, then keep stacking splash.
3. Merchant coin boost if the human-sized shop NPC is selling one.
4. Food track so you can eat during lasers.
5. Regen armor near 3,000 Gold heading into wave 50.
6. Walls and turrets after damage is real.
7. Class Gold is still a you decision. Engineer wants turrets. Snowman wants splash. Medic wants food. The GUI does not know your lobby.

If auto melee stays checked, you will own a legendary turkey and a dead fish pile. Uncheck it. The weapon tier list is not optional just because a toggle exists.

Playing with auto upgrade instead of full AFK

This is the less-boring mode. You still kite. You still jump green. You still call “fish” in co-op. The script only spends. That is useful during Golden Weekend when Gold income doubles and the shop outruns your brain.

Solo still helps. Pause still helps on private servers. Public 18-player matches will not pause for your GUI, and six people auto-buying walls is how the objective dies in silence.

Classes and Version 1.1

OneBed Studio’s Version 1.1 added new cats, bosses, weapons, perks, an Engineer class, a Vampire-class weapon line, and checkpoints. Auto upgrade scripts written before that patch may not see the new shop rows. If the GUI cannot buy Engineer or the new perk track, buy those by hand. Checkpoints mean a wipe is less brutal — do not let that trick you into skipping armor.

When the GUI fights you

• It buys walls at wave 8: disable wall auto.
• It buys melee at wave 30: disable melee auto.
• It never buys food: you will fail Floppa; buy tuna yourself.
• It opens every time you die: rejoin, execute once, do not stack loaders.
• It stops after a client update: the remote changed. Wait or play legit. See updates.

Scripts are not a build. Player builds still decide who stands on the fish. A GUI cannot be the Medic.

If both auto farm and auto upgrade are running and your character moonwalks into a laser, that is on you. Pick one combat helper. Keep one shop helper. Stay off green. Come back to how to play when you want to remember why the loop exists.
