The Portal is a beacon that you can warp to whenever you want. Once you drop the portal, a timer will be activated. The beacon can only be used once, and will disappear when used or when the timer reaches zero. When you warp, you will still fly in the same direction with the same speed. The portal can be obtained by collecting greens. The thing that the portal is used for most is probably warping to safety. You can drop a portal in a safezone or in an an abadoned part of the map. After that, you simply engage the enemy like you would do normally. If things look bad, you can hit Insert and warp back to safety to your portal. Sounds cool eh? But there's a catch! If an enemy player is near you, and if he has antiwarp turned on, then you won't be able to warp! You'll be stuck in whatever mess you got yourself into, and you will likely die (warping to your portal is usually a way to escape death ; no warp means no escape). The other important feature of a portal is (surprisingly?) the offensive part. If an enemy is chasing you, simply drop a portal. When the enemy passes the portal, you warp and end up right behind him, pounding him with a stream of L3 bullets. But be careful! Lots of players will use this trick against you too. Simply turn on antiwarp to keep them from doing this. In Warzone games, portals are used to gain control over an enemy base by surprise. Move into the enemy base, drop a portal, and move out again. You then have 60 seconds to get your entire team to attach to you before your portal times reaches zero. When you warp, you'll end up in the middle of the enemy's base with your entire team, usually surprising the enemy and conquering the base in a matter of seconds. Beware though, if the enemy is aware of your portal, they will have mined the hell out of their base. In this case, you and your team will probably die faster than you ever expected, and i'm not even mentioning the humiliation you and your team will face :) And the final thing you can do with portals : drop one, kamikaze with some teammates into the enemy base, and warp out as soon as you are near death. This way, you can get rid of some defenders, making it easier to capture the base. You can simply fire your guns till your energy reserve is depleted, and you warp out.
