E.P.

E.P. is an accronym that stands for Exact Position, or Exact Point.

E.P.s are used in Halo 1 to set oneself up perfectly in order to perform a Stunt. The Stunts that require E.P.'s are Bumps, and Balances.

E.P.s are usually transfered in the form of Screenshots. Players would take screenshots of exactly where to look in order to perform a certain balance or bump.

Using E.P.s
To use an E.P. in the form of a screenshot, simply take some immovable objects on the screen and relate them to the Reticle. For example, a rocket launcher reticle has a circle, with line going down and across it. An E.P. could refer to a point on the circle, or the lines themselves. You could make the connection that a line on the rocket launcher reticle points to a point on a vehicle, for an E.P.

Creating E.P.s
In order to create E.P.s, players oftentimes have to experiment continuosly. Thus, making E.P.s can be quite a drag. On multiple occasions, one must toy arround with thier movements, by jumping and then moving, to get to a pixel-precise location, thus generating the E.P.

Once the player has found the E.P., thier mind will make connections to how they have to line up to do it. Usually based on relative location. Which means thier thinking something like, 3 rows of pixels away from this line, and this line in my reticle touches this line.
