First off, do not pay over $5 for this because it is less than 4 hours long. So $1.25 an hour is a good deal. Also, the multiplayer is unplayable because it constantly crashes so I can't play it with my friend online and have to play single player only, which sucks because it is the most fun with a friend. But it is still a blast single player. It is like a combination of the oldschool arcade shooters NARC and Smash TV. You get to mow down hordes of bad guys and say hilarious badass action movie one-liners such as "explain that to your wife". You can blow the fk out of everything in sight and there are explosions everywhere like nothing you have ever seen before. ♥♥♥♥ gets bonkers fast and every level is like that from start to finish. The only downside is sometimes it can get stupidly hard but those parts are passable after only a few retries. I can also easily see how a lot of people would simply just not be able to beat the last boss because of how completely nuts the fight is. I got him on like my 5th or 6th try. The absolute best help you can give yourself in this game is to use a controller like I do (using a wired xbox 360 controller).
If you are lucky enough to play multiplayer with a friend, good for you. If not, it is still worth catching on sale for an absolute blast of a time. 0/10 unplayable MP, 7/10 SP. And if instead of blowing up huge stacks of cocaine bricks you could dive into them face first while inhaling deeply, it would easily be a 10/10.
