Long story short: if you can count on four friends to play online, then Bloodsports.TV can be considered as an entertaining game. Otherwise, if you can’t manage to find other players online to play, the game will deliver a forgettable experience.
Bloodsports.TV is a good hero defense game, without the pressure of games with PvP. Make sure you will be able to play it along with your friends, in order to enjoy it properly: although single-player matches are available, they take just a few time before they become too repetitive.
Bloodsports.TV offers some fresh ideas, but offers too little variance or reason to play long-term. A fun one-off co-op game worth a weekend, but don’t expect it to be a go-to.
