How to Play River City Ransom EX
Quick start
Select "STORY" in the title, check the game settings, and start from "OK". The first step is to wipe out all the enemies at the first Crosstown High School, then proceed to Styx Building 3rd Avenue on the right, to the abandoned tire factory, and defeat the boss Thor at the beginning. If you clear the first two areas on Alex's side and return to the high school, you will be able to recruit Gary early on. You can stabilize the game by picking up dropped weapons and cash, increasing your abilities with food at the store, and increasing your attack methods with skill books before moving on.
