Don't play it. Even for free. Even 5 minutes. Why? Let me tell you why.
First of all. Devs are thinking only about money from this game, they confirmed it here:http://steamcommunity.com/games/269390/announcements/detail/1621609200223087905"Q: Will there be any more updates, like heroes, to the game?
A: No, unless we get funding for that. "
They will not add anything to this game untill they will not earn money on it... It's most pure "♥♥♥♥ you!" said to the players and fans as it's possible. We all know - games must earn money to make them alive, but devs didn't released their game, just did only the outline of the game and are thinking only about $$$$$$$$$$$$$ from it. The game is not made for the players, only to earn money on it and abandon it after a few months.
Second thing. You can't connect using Steam since weeks. They are ♥♥♥♥ing on this problem.Q: How long will the servers be up?
A: Unknown, several weeks is an educated guess.
This game is made for a while. You know - one month, than it can be dead or kicked into trash bin. That's how devs are thinking about it. Do not let them be disappointed. Don't play it. Game will be dead faster than it's planed to be.
