Frontal energy cannons
The Pinger appears as a huge, heavily-armored tripod combat walker, roughly 18 feet in height. Its large triangular head has two tubes on each side of its head and two guns mounted under the chin. The two digitigrade-built forelegs act as the Pinger's locomotion while the third rear leg acts as a stabilizer when stationary. Each leg has three talon-like toes.
The Pinger's armor plating is colored grayish-silver with black tubing and details. The "eyes" and rear-mounted power core glow bright red.
Their name was first briefly mentioned in the trailer "The Wall" when a missing poster is shown of James Thomasson. There is a post-it reading "Last seen at Central Park. Pinger Attack." They were first shown in a teaser trailer for E3 2010. In a gameplay video for Crysis 2 at E3 2010, a Pinger was fought against and later shown in a cinematic.
After Alcatraz joins the Marines fighting the Ceph in Midtown, a Marine can be heard shouting to his squadmates to block their ears to stop the noise. This is assumed to be a Pinger, although it cannot be seen, due to Alcatraz's position in the sewer. Pingers appear in "Corporate Collapse", "Terminus ", "Power Out", and "Out of the Ashes", though only the first three can be fought directly; the fourth appears during the vehicle-riding sequence, where it can be destroyed with the IFV turret. Once destroyed, a single Pinger leaves behind 2,000 Nano Catalyst.
Follow the events of Crysis 2, Pingers are deactivated and left abandoned in the New York ruins and overgrowth until their reactivation by the Alpha Ceph.
A few can be seen in later levels and are somewhat uncommon. However the player will have some highly explosive weaponry against them laying around near one (usually an APC, JAW missile Launchers or C4).
The last Pinger to appear in-game is in Gods And Monsters near the secondary objective that contains an APC (though not drivable, its mounted gun can still be fired), some bots that can be hacked and the rare X-43 MIKE.
The Pinger is armed with the same energy-based chaingun utilized by the Ceph Gunship, as well as an EMP projector and a cannon similar to that of a Ceph Devastator. The shrieking-like noise it makes during normal operation and when firing its EMP is implied to cause large amounts of hearing discomfort or even pain, and is inferred to be the source of the name "Pinger."
The Pinger periodically fires EMP-based blasts that will completely drain the player's suit energy if close enough, and has the capability to know their position even when cloaked. If the player does cloak, the Pinger will stop shooting at the player, but will instead stop its patrol and start to fire EMP blasts at a more frequent rate. It also will look directly at the player, somehow knowing where he/she is, but will never fire its main gun. If the player goes behind cover, even while cloaked, it will fire an energy blast with a timed explosion behind their cover, and will continue firing them until it successfully flushes the player out.
Even though the Pinger's armor is thick, it can still be hurt. Its most vulnerable part of their body is the generator, which is identified as a glowing red object and damaging it allows for increased damage. Some weapons are more effective than others against the Pinger. The MK60 Mod 0 should be the player's staple weapon against one, but a weapon with the Gauss attachment also works; JAW's and packs of C4 (usually at least four) - if available - should be used against the generator. Though it takes some skill, an L-TAG can prove just as deadly as the JAW.
- In a pre-release TV commercial for Crysis 2, the Pinger is notably missing its third stabalizing leg it had in the final game. Also, the Pinger's red areas were more orange.
- Pingers can use echolocation to locate targets, revealed by Alcatraz in Crysis: Legion.
- The first Pinger the player faces in the end of the mission "Corporate Collapse" is named "MrPingy" in the Sandbox.
- Pingers are able to move around underwater much like the Ceph Gunship and the Warrior.
- In the Crysis 3 Crash Site multiplayer mode, players are able to go into the Pinger and use it as a vehicle.
- Pingers' shape and weaponry may be a reference to The War of the Worlds Tripods, given the energy based weaponry and the tripedal shape. (Unconfirmed)
