Super shield pack

The super shield pack increases your armor by 100 points to the maximum of 150.

When double damage is picked up, your weapon glows pink; for the time it is active, it will do twice the usual amount of damage it normally does.

Adrenaline pills, when picked up, give you 5 points toward your adrenaline meter. You also gain adrenaline naturally over the course of a game by fragging opponents. When your meter reaches 100, it can go no higher, and one can enter an adrenaline code in order to gain a special powerup ability.

In bombing run games, the objective is to collect the ball (the player with the ball has glowing lines around him in the color of his team), take it to the enemy goal, and either launch the ball through the goal (for three points) or jump it through (for seven). When collected, the player's weapon changes to the ball launcher; the player cannot fire another weapon whlie he holds the ball.
