Xradar is a ship upgrade, an item that you can use over and over again until you die, or until you lose it because of damage. Upon activation, Xradar will reveal all stealthed and / or cloaked enemy ships on your radar. It costs energy to maintain, and it will simply stop working when your energy is depleted. Some ships have xradar enabled by default, and therefor cannot lose it due do damage. Other ships will have to collect greens to obtain xradar. Xradar is an invaluable item in any zone. Whether you're flying around on your own, being driven around on a huge turret, or if you're playing against 10 other teams, you will simply need to see cloakers and stealthed people in order for you and your team to survive and win. Usually it's better not to keep it on permanently, simply because it drains your energy reserve. When you forget to turn it off when going into combat, you can get awfully low on energy. Switch it on and off quickly every now and then rather than using it continuously. If you do it right, no cloakers will get close without you noticing them in time, and you will have more energy to spend. If you don't have xradar, try to green for it asap. A Cloaker will often fire a volley of bullets at you and cloak again, waiting for your reaction. He will notice when you don't have xradar, because your flying pattern will be different than when you can see the cloaker. He will try to sneak up as close as possible, killing you within seconds when he starts pumping L3 bullets into you. The best thing you can do is run to a crowded area, or try getting rid of him in a nearby structure. In open space, you can rocket away from him or lay some mines behind you. He will have trouble keeping up with you because of other ships and bombs flying around. He has to fly around any mines you drop, because he has little energy to spend due to the use of cloak and stealth devices. He can turn them off though, but that will only make him an easy target for other players. If you lure him into a base, you can burst him to death in a small passage (when you think he's near). You can hear his ship bounce off the walls if he is cloaked, use this to your advantage and try locating him with gunfire or bursts. Don't use bombs unless you are sure that there's some distance between you and the cloaker; if he's right next you, your bomb will explode in your face, causing massive damage that will bring your energy near the red zone. Always mine the path behind you. A Cloaker can't get past mines unless he reveals himself by either running into the mine or repelling. He will try to avoid this at all cost, which will probably buy you enough time to escape. If he does reveal himself, you have a decent chance to strike back even if he's cloaked. Again : try to avoid using bombs ; use guns and multifire instead. Try to bounce around a bit so that a sudden straight line of bullets from the cloaker will be less likely to hit and damage you severely. Try to make the battle last as long as possible ; your recharge rate is much higher because of the cloak and stealth device the cloaker is using. This is the one advantage you have, so try to get the most out of it. Turn on stealth to force the cloaker to use xradar too, causing an even higher pressure on his energy. Wear him down, run alot and try hitting him with a few rounds of multifire as you do. Finish him off with a sudden thor fired at him when you bounce back off a wall. If you feel that you can ambush him, simply drop a portal in a corner and fly away. When you think he is near the corner, warp to the portal and fire your burst and watch him splatter against the walls.
