The 2015 Sonic Hacking Contest‘s contest is nearing an end and this has to be the wildest one I’ve seen this year. Someput put a Portal gun in Sonic the Hedgehog 2!

That someone is snkenjoi and his small team of assistants E-122-Psi, flamewing, iojnekns, and FraGag.

The Portal gun works just like it does in the Portal series. Pressing A along with a direction throws a blue portal, while the C button and a direction throws an orange one.

What I was surprised to learn is that the portals can affect more than just Sonic himself. You can use them to send enemies’ projectiles right back at them.

You can download the hacked game here to play on PC. You can browse all of Sonic Hacking Contest 2015’s entries here.

Below is a full play-through of the game with the Portal Gun, showing off what the hack can do.
