In Tiberian Sun and Firestorm, crates look like grey polyhedrons consisted by pentagons and feature a diversity of contents;they also sometimes serve as mission objectives (e.g. Retrieve Disruptor Crystals). In skirmish and multiplayer mode, a crate's content is always random, and can both benefit or hinder the player's units/gameplay. Sometimes when picked up, a symbol will appear for a few seconds to indicate what bonus/punishment is contained inside the crate.
