Inevitably we missed some releases as we’ve been offline for a while. One of them is Bloons Tower Defense 4 by developer Ninja Kiwi, which has been in development for a whooping 419 days. Since its release, the game has been enjoyed by millions of players and received exremely high ratings.

Ninja Kiwi has not only stretched out the whole scope of the game with more bloons, towers and maps, but in doing so they’ve been able to stretch out the difficulty of the game. The easiest mode is far easier than it was the case in Bloons Tower Defense 3. The hardest levels are truly insanely difficult this time. With this they hope to bring you all a much longer playing experience and something that people will enjoy playing for at least the coming twelve months.

There’s no word yet on a fifth game and don’t expect to see it arrive this year. For all of us who haven’t played this one yet, you’re missing out!
