How to Cheese the Mutiny Ending with SMK Shells in Iron Nest Heavy Artillery
1. If the SMK shell lands near friendly units outside the city: it takes effect normally and does not trigger the counter-battery timer (this applies to underground units as well, which require armor-piercing shells to deal with).
2. If the SMK shell lands inside the city: it triggers Ending 1.
3. If the SMK shell lands in a location that changes the position of one or two five-star units: it triggers the counter-battery timer, turns friendly units into enemies, and makes the Conscription Table unusable.
