. It's more like a learning version, it's main focus is to get you acquainted with the three heroes and with their powers, and also set the ground for the main action in Retribution.
So, from a chronological point, you should start with Prologue instead of Retribution, so you can learn the story from the beginning and get to know the characters. But the action is much more intense in Retribution, because of the more challenging levels and because of the aliens...and the wacky alien bird that is flying around and which you can smash with boxes or barrels..or you can just watch it get smashed by giant boulders...or blown up into pieces when touching a laser grid
If you like I will send you a promo code for Retribution for you to try it out, in exchange for feedback that could help me improve the game in the next updates
