Sydney wears military boots, trousers, kneepads, gloves, a blue leather jacket with the GDI logo on the back and a tank top. She has brown hair and a small necklace.
Sydney's Personal Ion Cannon has moderate range, very low rate of fire but very high damage in a single shot; therefore she is best employed at taking potshots against enemy vehicles, possibly finishing off damaged ones in the process of retreating. Against fast moving vehicles, it is advisable to aim at the spot where they would go next in order to hit them. After firing once, a Sydney should pivot or seek cover until her weapon has recharged.
Sydney is able to deal high damage against infantry as well, her Personal Ion Cannon is effective, but the slow recharging sequence and wind-up of her weapon will prove costly, especially against infantry with automatic weapons, should she miss a shot; therefore, her Personal Ion Cannon's effectiveness against infantry is determined by the player's aiming skills and reflexes, akin to sniper characters such as Deadeye or Havoc. Her secondary weapon, the Tiberium Flechette Rifle flings health draining tiberium shards at a rapid rate, and with a high headshot multiplier, has the potential to down even the toughest anti-infantry characters if utilized effectively. It has a small magazine so it is advised to take careful shots so as to avoid having to reload during a firefight.
Sydney share the same weakness that snipers have: she is usually at a disadvantage if players get close to them; infantries such as Chemical Trooper, Officer, and Mendoza are preferred for their high rate of fire when confronting her in close quarters. When approaching her, strafe and jump around with alternating movement so to not follow a predictable pattern to raise the chances of avoiding a headshot; even so, a veteran Sydney might still be able to snipe your head even when you are moving around.
For Vehicles, Sydney will prove to be a serious threat, jumping out to fire at you and then falling back into cover. Usually she will strike at you from infantry paths, so you cannot ram her over. Laying suppressing fire with APCs or tank shells will not work very well in this situation. It is best to either retreat, have some Engineers backing you up, or just remaining around to act as a distraction in order to allow teammates to deal with her.
