Bought it day 1 and finished the only 5 levels on day 2. No replayability as the few maps are always the same. The only benefit is for buying costumes or adding to you perks so you can be the same strength at a higher difficulty without any sort of reward for putting in the time. The game wasn't cheap. $10 less than some new games that have waaay more content just to have to put more money in if you want to have more than 3 builds. 3 different ways to play makes this an indie game at best with micro transactions. Except it doesn't cost $20 and doesn't offer anything to keep grinding.
Definitely a cash grab without concern for fans. (Did I mention how when you move around the volume goes waaay up and down where you can't hear player banter or weapon attacks because you aren't facing the teammate casting it instead of having the audio be distance based or adjust gradually). Truly disappointing. Reminds me of a baseball phone game with loud triggering thwacks that make you want to hear the home run bat sound more so you pay to unlock more costumes to make the game more fun for longer even though your not playing anything new or challenging. And I wouldn't pay for that if I knew better either. Sadly just garbage.
