There are a lot of addictive Flash games currently available on the Internet. The horror point-and-click category game The Visitor: Massacre at Camp Happy from ArcadeBomb.com of the best for hours of somewhat-mindless, challenging entertainment.

A group of campers decide to leave the campground to take a hike up the mountain to watch the meteor showers. One camper, Stacey, decides to remain behind in a tent. In the meantime, a meteorite hits the ground and releases "The Visitor" -- a reddish alien slug based on Zeebarf's "The Visitor" game. The goal is to help The Visitor eat the 10 campers as it moves through 11 scroll-style levels of the forested Camp Happy.

The game also The Visitor with different types of animals to eat. Devouring these animals gives the hungry alien their abilities, such as swimming, flying and climbing, so he can easily navigate Camp Happy's terrain. Success is measured with points and achievements. Extra points are also given whenever The Visitor destroys or knocks over things like tents, signs, tables and trees.

The game uses a five-key control system with keyboard arrow keys serving as directional and movement tools. The spacebar opens the alien's mouth. The "W," "A," "S," "D" and "Ctrl" keys do the same, respectively. A player can reset the previous level at any time with the "Esc" key.

The Visitor can die. Death typically happens when the alien fails to eat an animal that is too big or facing him when he attacks. When a larger predator attacks, The Visitor slides backward leaving a blood trail on the ground. A health meter shows how much "life" The Visitor has remaining. When there's no more, he turns into a pulsating purple mass and a new meteorite falls releasing a new "Visitor" alien.

Note about game play:

It can be difficult to eat larger animals even using the game's hint of sneaking up on them. Additionally, the terrifying music and copious amounts of blood might be too much for some players to handle. The music matches the game's theme fantastically, but it's often so loud it sometimes becomes distracting. Thankfully, there's a mute option.

The game also offers two video walkthroughs for players who have difficulty succeeding in certain spots. These are accessed by clicking the icon below the bottom right corner of the screen that looks like an arrow inside a circle. It is next to a four-arrow icon.

And now, you should check out the Visitor: Massacre at Camp Happy! You won't regret it.
