Happy Wheels Hacked is a simple, easy to play arcade type game whose main draw is its physics engine. For those not familiar with that phrase, it basically means that the playable characters and the vehicles they use react dynamically with the environment as normal objects would in real life based on their speed, weight and angle of contact.
The premise of the game is to get your character to complete an obstacle course in the least possible time. You start off on a vehicle, bu you may jettison it if the need arises. The character and vehicle combinations include a man in a suit on a Segway, a very old, very diseased looking guy in a wheelchair, a bicycle with a father pedaling and a young child in a chair seat behind him, and a morbidly obese man on a four-wheel motorized scooter (complete with a basket of junk food).
What is the Hack?
Happy Wheels Hacked gives you the benefit of unlimited health - you character can take a beating against the walls, floor, obstacles and fall from incredible heights over and over again, and then simply get back on his vehicle and play on.
The controls are exceedingly simple - the game is played primarily using the four arrow keys. Up accelerates the character and Down decelerates them, and their use is fairly straightforward. The Left key makes the character lean backwards and the Right key makes them lean forwards (movement is towards the right of the screen). These two actions allow you to control the angle and tilt of your character to balance them on the obstacles.
Besides these, the 'Z' key allows your character to jettison his vehicle and interact directly with the obstacle course. The Spacebar comes into play only after a character has ejected from his vehicle - it allows him to grab onto the various protrusions and overhangs that feature on the obstacles.
There is a wide range of innovative obstacle courses, including BMX parks, mountain cable cars, a zombie-infested town and even the digestive system of a huge monster that has eaten you to satisfy all your obstacle-clearing cravings. However, if that is not enough, the game features a detailed level editor to allow you to design the obstacle course of your dreams. You can pepper it with landmines, spikes, wrecking balls, buildings, meteors and balls to impede progress and springs, fans and boost passages to make it easier.
