Run 2 is the second installment in the Run series. It was published on March 21, 2011 by Player 03, but is no longer being updated. Run 2 is non-canon; it does not have a storyline, or fit into the plot of Run 3.
In Run 2, you play as a gray alien running through a series of many different levels.You must run across long levels sometimes while avoiding obstacles and gaps in the floor. If you fall off the stage, the level will reset and you will have to start again. You must take advantage of the unique gravity system, with some levels requiring the player to jump onto sideways facing blocks or even blocks above them to progress to the next level. When a wall or ceiling is touched, the character will "catch" onto the new surface and the gravity of the level will flip and the character will run on the new surface as though it were the floor. It is necessary to use this unique gameplay mechanic to complete many levels. However, some narrow, dark surfaces cannot be caught onto.
There are bonuses that can be collected, which appear as glowing yellow dots. Besides being a collectible, bonuses will unlock bonus levels if enough are earned. There are 31 bonuses for each character, one in each level as well as bonus levels.
Run 2 is the only game to have another character besides the Runner available from the start. Both the Runner and the Skater are default characters, as well as the only playable characters in Run 2. Progress is saved separately for each character, counting the levels completed as well as the bonuses collected by that character. There are separate levels for each character, although they usually have similar patterns of obstacles.
The Runner is slightly slower than the Skater, but she has better maneuverability and sideways movement on the ground. In comparison, the Skater is much faster and jumps further, but is harder to control.
