Whoa whoa whoa, I already beat this game with the cannon ending. So why am I playing this game again? The reason being is that although you play as both characters both times, if you start with the opposite character, you technically get a different story. Besides, come the 2nd half of this run, you'll see why I didn't really care how it went, enjoy!
"Last time, we discovered that William Burken (in his first G-Virus form) actually takes more than just one RPG to the face before he plummets to the ground. So yeah, this technically could've been split up into two parts. But you know what, it's only about 50 minutes long, let's just finish this once and for all."
