Tumblebugs 2 is an effective, entertaining, challenging, and addicting game only available on Windows, which is also part of the group of PC games with category Adventure. As for its story, it follows an alien race called the Turkeys, who have landed on earth to survey and observe human activity. When they realize humans are aggressive towards them, they decide to take over the land and make humans their virtual slaves. Because of this, they need to train two new human species - Bluefish and the ever-popular Chuckfish - so they can fight off the evil humans.
As for the game itself, it follows a simple storyline. For instance, one level will have you controlling one character, the Bluefish, while the other levels will have you controlling the Chuckfish. Each character has its own moves and skills, so it's up to you to think logically and strategic on how to make use of your character's strengths against each other and against the enemies. Because this game is all about strategy, you're likely to come up with many different techniques of fighting and attacking against the enemy.
However, one thing that makes Tumblebugs a very challenging game is its graphics. The reason why is because, since this is a first person shooter game, you need to really see what you're targeting with your mouse. The good thing about the graphics is that it is fairly well integrated into the gameplay and the controls are not too stiff or clunky, making it much easier to master the game. What's also good is that the game is not repetitive, as some games become. You'll find yourself playing the game over again, just to discover the different secrets and powers you unlocked along the way.
