Attachments

Attachments can be gained by using Weapon Upgrade Kits; up to four can be attached to a single weapon.

Using a Weapon Upgrade Kit gives a choice of 3 or more randomly-selected Attachments for the currently equipped weapon, along with a small boost to its damage (+5%). Attachments with a gold color are rare attachments, which have a low chance to appear as an additional choice in the given selection.

Trivia
The digital screen on the Digitalizer upgrade displays the word 'SHRIKE', the screen name of one of the developers.
