How to unlock the Great hero achievement in Castle of no Escape 2 - Definitive Guide
Killing 10 and 15 enemies is accumulative so dying does not matter, just killing and both will pop. Took me just a few minutes.
Use the exact same strategy as in I love money (200G) to quickly grind out kills and unlock these achievements while working on that achievement.
