The Disguise Kit is the stock PDA weapon for the Agent. It allows the user to disguise as an enemy or a teammate. Disguising as an enemy will allow you to use enemy buildings and mediguns. However, you can still be hurt and take debuffs. Although disguising as a teammate seems pointless, you can disguise as a key ally such as a Doctor and trick them into following you into a sentry nest. The Disguise Kit is an important tool for the Agent as it decreases suspicion and nullifies building usage. But sometimes it is better to not disguise at all because disguising (unless cloaked) will create a team-coloured cloud no matter which team you disguise as.
