Don't bother. You can't play this. You need friends.

Do not play this game.

This game is not easy. This game is not fast. You will die, you will fail, it will not always be your fault. You will be forced to rely on your teammates or become good enough not to need them at all. Very few people still play this game so finding a team will be difficult, but not impossible, beating this game without a team, and a damn good one, is nigh impossible.

I beat this game, it took a village and an age. If you really want this hardcore experience you'll buy the game anyways, and you will probably enjoy the grueling climb to the finish. The rewarding feeling for completing the game is not something you'll find anywhere else like this game has to offer, a sense of achievement for overcoming this senseless onslaught of brutality dragged out over countless slogs of levels. A victory well earned.

But if you're not sure you want to invest that kind of time into a game, if you don't want to gamble your success and hours out of your day on the competence, cooperation, and altruism of 3 random strangers, don't buy this game. You will not finish it, and I very much doubt you will ever come to enjoy this game, and if you have these doubts, I urge you, do not buy this game.
