The Giant Death Robot is the end-game tool of destruction for the Domination Victory seeker. It is titanically strong, it attacks from afar and can even move through water without Embarking! Despite its great size, it can also pass through Mountain Tunnels and Qhapaq Ñan.
Unlike every other military unit in the game, the Giant Death Robot does not gain promotions, but instead gains bonuses and boosts through specific technologies in the tech tree. These include Movement and strength bonuses, the ability to jump over Mountains, and a particle beam cannon that essentially gives it a bombard attack for taking down city defenses. When it comes to combat, the GDRs function similarly to the Persians' Immortals, as they are capable of both ranged and melee attack, so make sure you click the ranged attack command instead of right clicking when you want to use them to take down city defenses.
However, the Giant Death Robot is not a one-man army! For example, a Modern Armor Army will have a Combat Strength of 112 (which is pretty close to the GDR's), while the GDR itself cannot form Corps and Armies. After the update of aerial units, Jet Fighters have a Ranged Strength of 110, which will make for decent damage against the GDR (especially without its Drone Air Defense upgrade). As in Civilization V, a focused attack by several units will be able to bring down this robot, so don't expect it to defeat everything on its own.
The Giant Death Robot counts as neither a land unit nor a naval unit, which means it will never have to embark/disembark (and thus will not receive extra Movement from Mathematics or the Great Lighthouse), exerts zone of control on both land and water tiles, and is unaffected by all Great Generals and Great Admirals (but is still affected by Supply Convoys). That also means this unit can never be purchased with Faith, either through the Grand Master's Chapel or by Gitarja's ability.
The Giant Death Robot's great size and sturdy construction make it resistant to nuclear weapons. A direct hit from a Nuclear Device or Thermonuclear Device does 50 damage to it, and fallout from nuclear strikes doesn't damage it.
Finally, the Giant Death Robot needs quite a considerable investment in time (its Production cost will take most cities 15+ turns to finish, though slotting Integrated Attack Logistics will expedite this), money (only very well-developed empires can easily amass 6000 Gold), and resources (3 Uranium to maintain a single GDR is no small thing). Only the mightiest empires will be able to afford it on their way to victory.
Almost no one calls them Gunnery Deployment Rigs, because pop culture anticipated the rise of the bipedal combat platform for more than fifty years prior to the first operational deployment of a GDR, and has given them dozens of evocative names: Mechs, walkers, Giant Death Robots, and so forth. There is something psychologically affecting about seeing one stride across the landscape—reassuring for friendly forces, and terrifying for enemies. There is a certain purity to the GDR, a recapitulation of the human form, as well as an improvement on it.
The GDR is not a stealthy weapon, but it is an effective one. The use of a roughly-human anatomy allows pilots a more intuitive grasp of the weapon and defensive systems, and allows motion feedback systems to tap into human locomotion to assist. Indeed, some people regard the locomotion controls of the GDR to be the most impressive advancement in the entire system.
- This incarnation of the GDR was initially called the Gun Deployment Rig.
- In the livestream that introduced this new incarnation of the GDR, one of the developers stated that they intend for the Giant Death Robot in Civilization VI to be, in effect, a Wonder in the form of a military unit.
- Also in the same livestream, it was revealed that a number of other new units planned for the Future Era had been deferred in order to concentrate on development of the GDR and its upgrades.
- The Gundam has been credited as one of the influences on the design of the new GDR. Others include Neon Genesis Evangelion and Pacific Rim.
- The new GDR originally came about as a result of discussions on a potential Future Era unit that could merge the light and heavy cavalry lines in the unit tech tree.
