Part 5 of playing Gunstar Heroes on PS3 went as well as i thought it would. In part 4, https://youtu.be/OxdokqLjspU, i had already spent around 30 minutes trying to save Yellow, but couldn't. So this videos continues on from that.
From part 4 i have have two save files, one near the boss with low health and one a little bit into the stage with most of my health. i play both of them before settling into trying to complete the stage with more health to make the boss fight easier. The problem with the boss fight is that whilst i had learned the moves he uses, he was unpredictable and there wasn't a pattern to learn. it felt like a combination of luck and unfairness. But at the end, i did defeat him and save Yellow.
