Girder

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 player's Worms from incoming threats, or block the opponent's Worms.

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.

1st/2nd generation games
Once the Girder is selected, the angle and length can be adjusted by pressing the left and right arrow keys. In 2nd generation games, it can double in length after one full rotation.

3rd generation games
Once the Girder is selected, the angle can be adjusted by pressing the middle mouse button or the Jump Button. Unlike 2nd 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 (except in Worms Forts: Under Siege, where Girders are square wooden platforms with a default size about the same as the top of a Tower, but they also have a much larger size which can be toggled).

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 Blow Torch, 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 2nd 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.
 * In Worms 4: Mayhem (and possibly Worms: Ultimate Mayhem), there's an unchangeable limit to the amount of Girders that can be placed in one round, which is precisely 45 Girders. Once the limit is reached, the Girder can still be selected from the Weapon Panel, but no matter where you move it, it stays red, indicating that it cannot be placed anywhere. Regardless of who placed the Girders, no more can be placed by either players if 45 Girders are present in the round, and drowning or even destroying some of the Girders wouldn't let any of the players place more.
