Infinity Route:

1. Be on Agony Mode

2. Kill Ross

3. Have at least 40 kills (The enemies on Last Autumn count, including the shadows)

4. On the melting village, find the secret entrance, go through the cave, and on the other side, fight the secret boss

5. Win (if you escape or lose, you won't get the Infinity Route)

6. Proceed like normal

Redemption Route:

1. Spare Ross

2. Reject either the first or second Fold of Infinity (Better to reject the second one, so you can have Denier Fist)

3. Proceed like normal, Ross will be alive in the cave after the Bloody Cliff (The one Arnold jumps from to escape the Horde)
