Yes, its true what many have said, this game is not 100% there yet. Glitches and bugs are common throughout game play, but I have yet to encounter any that "really" impact game play or progress. It does feel a bit unfinished, but those parts that do feel finished, are very good. The character likenesses took a little getting used to, but once you do, they are fine.
Scenes/missions end rather abruptly, leaving precious items on the ground that you would have like to have collected, however, you are immediately taken back to the jet once the last enemy in a mission is killed, this is rather annoying.
They did a really good job with Ms. Marvel's story line, but honestly, the female characters are really pretty under powered, so, Im not sure why you would ever select them for a mission, unless the game makes you.
The power ups are a little complex, some dev went way overkill on that whole system.
All in all, its fun, its familiar, and easy to step in, play a few missions, and step out, without having to remember what you were doing, and what you needed to do next. (unlike many games in this genre)
There are no 1/2 star options here, so I opted for a 4, but its a solid 3.5.
