Rules are
1. Only the starting handgun
2. Only flash grenades are allowed
3. Knifing is allowed but not overly abused
4. 1 upgrade per merchant (if available)
5. If a boss is killed without dying or reloading I am allowed 2 upgrades per merchant visit (if available)
6. After 3 deaths the run is over.
