Girder

The Girder is a utility that appears in all Worms games. It is a long thin piece of metal platform that can be placed by the player. Once placed, the Girder has no special properties over the rest of the terrain. It is usually used by players to make a piece of platform to prevent their Worms from slipping into the water, but is most often used to protect the players'/enemies' Worms from incoming threats.

Girder Starter Pack/Bridge Kit
The Girder Starter Pack is a utility in Worms Armageddon and Worms World Party which allows the user to place up to five Girders in one turn. From Worms 3D onwards, it was renamed the Bridge Kit.

It is unlocked in Worms 3D in the campaign mission "Beefcake Breakfast Brawl"-- on the roof there is a Utility Crate on a platform. Low Gravity must be used to reach it. Collecting it will acquire the Bridge Kit in the mission and unlock it for use in multiplayer.

First/second generation games
Once the Girder is selected, the angle and length can be adjusted by pressing the left and right arrow keys. In second generation games, it can double in length after one full rotation.

Third generation games
Once the Girder is selected, the angle can be adjusted by pressing the middle mouse button or the jump button. Unlike second generation games, the length cannot be changed.

3D games
Once the Girder is selected, you can only move it, then place it. The length cannot be changed.

Tips & Tricks

 * You can use the Girder to jump over a big gap.
 * Use the Girder as a defence from weapons. Be careful, that some weapons can even pierce through Girders easily such as the Bunker Buster and the Blowtorch, dealing your Worm some damage.
 * The Girder is usually limited, so spacing them out means you may not have to use as much of them, and since your Worm can jump, you usually won't be at risk of falling if you are careful.

Trivia

 * In second generation games, there was a glitch that allowed Girders to be placed over anything, even Worms. This was fixed in a beta update.
 * In the 3D games, the Girder has a much different shape. While the Girders appeared to be long and thin in the 2D games, they're much thicker in the 3D games.
