You folks requested it, and now, here it is! The Genocide run boss battle with Sans! I hope it lives up to expectation~ It was pointed out to me that the lack of battle SFX did take away some of the energy of the fight, so I found an SFX pack for Undertale and plugged 'em all in!
(You can also see how bad I am at this game UGH THIS FIGHT IS HARD WAH I DIED LIKE 15 TIMES)
Voice acting done by me Sound effects taken from Freesound & Undertale Undertale was created by Toby Fox and it's SUPER DUPER GOOD! Check it out on Steam!
