Now here is something really crazy. From the looks of it, Resident Evil 4 Ultimate HD has a fully functional Tyrant (including the 3D model, AI and data) from Resident Evil Remake.

For those unaware, Resident Evil 4 Ultimate HD is a refined PC version of RE4 that came out in 2014. This version featured native keyboard and mouse support with customizable key binding, mouse sensitivity, and mouse acceleration settings. Moreover, it came with support for 60fps.

On the other hand, Resident Evil Remake originally came out on Nintendo Gamecube in 2002, and found its way to the PC in 2015.

Seems Tyrant AI & data from REmake was leftover inside RE4 UHD, is able to be activated with only 8 bytes changed in memory: pic.twitter.com/gHV3AWum0T

What’s crazy here is that you can activate the Tyrant and fight it. So, if you own a copy of the game and want to fight the Tyrant, you can do so by following this guide.

Have fun!
