Video showing all off-guard/betrayal kills in Undertale. These are kills where attacking a monster at its most vulnerable moment will kill it in one hit. Experimental quality.

0:00 Toriel
3:15 Papyrus
9:18 Shyren
10:21 Royal Guards
12:58 Muffet
14:23 Sans


Despite the low damage with Shyren, it is actually is a special kill, normally it'd only do about 50 damage and it wouldn't kill.

Sans segment is actually two parts strewn together.
First part: huffyuv → raw avi file → ProRes → lagarith → x264 → YouTube
Second part: ffvhuff → H.264 → lagarith → x264 → YouTube

The bonus hardmode footage is: lagarith → lagarith → x264 → YouTube

Want to see an almost lossless video that's just lagarith → lagarith → YouTube? See this:    • Undertale - All simple reload alterat...  
It would be lossless if a certain video editors weren't so bad and don't enforce bilinear resizing.

although you probably don't care about any of this
