Personalize your games safely with WeMod

WeMod is always safe and always free because of our community of millions of gamers around the world. We are supported by WeMod Pro subscribers. Check out our reviews on Trustpilot.

How do I use the cheats in Undertale?

WeMod will safely display all of the games on your PC. Open a game from the list and simply press play. After the game loads and once you’re in-game, you can start enabling different cheats!

Will this work with my game version?

WeMod uses advanced technology to detect the game version you’re running and will let you know if it’s supported. If it’s not, you will still have the option of giving it a try or requesting an update!

ReliableFlame6761 Love the UI and how it's simple to navigate, how it shows which games you have and makes it easy to enable which cheats to use!

DynamicLeaf8571 It was Great to play honestly i get to see so many iconic fights and scenes and i get to see the lore because i skipped the fights with wemod.

MDJ2k13 Yo thank you so much, I always do a pacifist run because i suck at genocide undyne, but with this, I can finally do a genocide run and then turn off the mods when i get past her!

RandomSquirrel782 The unlimited health was so good, i was on my pacifist run then i went to core (i hacked undertale so i got true locket early) but the core enemies we're to strong and dealt 2-5 damage each hit, i pressed 1 and it was a no problemo!

doubleao The trainer shows a false positive for anti-virus as trojin. I'm not sure if any way for you to fix this. I'm sure you've had others report on this.

intrusive everything worked out well! Dont level up your soul too much or you will one hit everything and mistake it for the max attack being broken

EagerMoon180 I wished there was a speeding up mod like I can walk faster and time goes by faster such as on cheatmod but I guess I could always use cheatmod.

TFrock It works really well except the turning the cheat off part. Thanks! I even tried cheat engine and that dident even work so cuddos to the dev of this!

GasterLeftForMilk This is actually so cool, how the mods affect the game files enough to actually change it, but it doesnt ruin the plot, story, or really anything. 10/10. Thank you for this.

HP_D_06 could use a couple more features, still amazing though!!! requesting the ability to skip turns and ignore battles, maybe even insta-spare battles.
