Expect more of the same, but worse ever so slightly in execution. Many of the levels exhibit either sloppy texturing, odd lighting, long load times, bad performance or a mix of all of the above. More than that, the whole expansion doesn't come across as one coherent campaign despite the underlying story and the fact that the long missions follow after the short ones. For example, only two of the levels offer collectable messages, and only in one level are they spoken messages. Some of these levels also have some of the nastiest difficulty spikes of the entire game. In fact, the very first level might be the hardest, which again hurts the idea of this being a progressing campaign. With that said, there's fun to be had - it's still Overload after all - and some of the levels like SAO Outpost are on par with those of the main game. Given i payed less than 2 bucks, i can't complain too much. Just don't expect the quality of the main game.
In this game, you walk around a lot and annoying teenagers (i didn't manage to kill any of them in my playthrough; your experience may vary) talk to you constantly. Sometimes you get to a ledge. You have to then press spacebar to climb up or down. There are also intersections in the road. Furthermore, you possess a radio, and you have to tune in to specific frequencies when the game tells you to. In the dialogues, more often than not, you can respond with one of three options - if you catch them in time that is. That way, the game enables you to shape the story and the character relationships the way you want. If you still find yourself caring about any of it after hours of this, you may actually roughly understand what the underlying ghost story is about. Oh, and it's kind of like Stranger Things, so everyone, go get it!!!
