How to get Genocide Route in UNDERTALE:

You MUST kill ALL "Bosses", (except secret ones, those are optional).

In the Ruins it MIGHT not tell you how many monsters left to kill, (you have to kill 20).

You should 1-shot all bosses, (except Undyne The Undying and Sans), if you're doing it correctly.

It should tell you how many monsters left to kill from Snowdin/Ice forwards from the save points.

After finishing the kill-counter, every encounter should say "But Nobody Came".

Note: In Snowdin you HAVE to kill "SNOWDRAKE" before the kill-counter finishes, same with "SHYREN" in Waterfall
