Kane's Challenge, also called The Gauntlet, is a console-only mode included in Kane's Wrath. It is a gauntlet of battles where the player chooses a force and competes against various armies. Players on the PC get Global Conquest instead.
Available armies include basic GDI, Nod, and Scrin armies, as well as two specialized sub-factions for each; the Steel Talons and ZOCOM, the Black Hand and the Marked of Kane, Reaper-17, and Traveler-59. The Nod leaders who administered the test included the GDI and Scrin factions as a way of adversarial training; to allow the prospects a chance to learn the strengths and weaknesses of each army.
Kane himself briefs the player during the tests; giving a brief history of the force the commander selected, as well as a congratulatory speech following a commander completing all simulations with a faction.
There are ten stages to Kane's challenge, pitting a candidate against all of the selectable factions. Each mission begins with the candidate having a single construction yard, typically located near a Tiberium field for resources. The opposing force would have their own base already set up; and would generally attempt to expand across the map. The stages became progressively more difficult, with the opposing force having larger, more defended, or even multiple bases. The stages were, in order of appearance:
