Colonel Autumn

Colonel Augustus Autumn is the commanding officer of the Enclave Armed Forces in the Capital Wasteland by 2277.

Autumn's father was a high-ranking Enclave scientist. When after the destruction of the Oil Rig he received orders from the new President, John Henry Eden, telling him and all surviving Enclave troops to relocate to the Raven Rock military base on the opposite end of the country, he obeyed the order. Augustus' father gathered his troops and their equipment, and led his men through the post-nuclear United States. Upon the Enclave's arrival to the Capital Wasteland, he was the only one privy to the fact that John Henry Eden is actually a ZAX unit that has achieved self awareness. After his death, he passed that knowledge to his son, who by that time became the leader of the Enclave's military.

Autumn followed Eden's orders as a good soldier, although the colonel indeed had his occasional disagreements. Autumn overtook Project Purity and seemingly died when James flooded the project's chamber with deadly radiation. However, he managed to survive by injecting himself with a mysterious medicine - likely the Enclave's more powerful equivalent of Rad-X or Rad Away.

The tension between President Eden and the colonel finally snapped Autumn's loyalty, as he disobeyed the President's orders and usurped command over the human contingent of the Enclave forces and relocated them to the Jefferson Memorial, to make their last stand.

Colonel Autumn shows no regret over actions such as shooting unarmed captives; he actually executes the player in the event that he or she surrenders the actual code to Project Purity. However he is not completely heartless, as he is able to be reasoned with during a final encounter, and (according to President Eden) actually objected to placing the FEV into Project Purity to kill all contaminated humans in the region.

Autumn's fate
Autumn is confronted by the player at the very end of the game's main quest, just outside the Purifier control room. He is accompanied by his two personal bodyguards, a pair of high-level Enclave soldiers equipped with Tesla Power Armor and Gatling Lasers.

Surprisingly for the game's final battle, Autumn himself has fairly average durability, being only marginally more durable than a Talon Company Merc. He does wield an incredibly powerful customized weapon, however, and his two elite Enclave Soldier bodyguards are very tough, being probably the most durable enemies you'll face (outside of Deathclaws, Super Mutant Masters, and unique bosses like Vance or Commander Jabsco). Still, with Sarah Lyons and Fawkes (or another companion) backing the player character at this point, the fight should be fairly effortless.

There is more than one way in which Autumn's story ends, which is the player's choice.
 * He might be killed in combat by the Vault 101 Dweller in late 2277.
 * If the Vault 101 Dweller so chooses, he may argue with Autumn and let him live, whereupon he and his personal guards will simply leave.

Equipment
Colonel Autumn wears a tan trench coat over his jet black uniform and uses two weapons, both custom made: an N99 10mm Pistol and an AEP7 Laser Pistol.

It is possible to acquire this equipment before the the final showdown at the purifier or without using cheats if Autumn manages to "glitch" out of the purifier room.

Autumn's trench coat is an average armor, roughly equal in protection to Vault Security armor, and though twice as powerful as a standard 10mm pistol, his custom version is still quite weak. However, his customized laser pistol is one of the most powerful weapons in the game; it's almost as damaging as the Alien Blaster (although without the increased critical chance multiplier) and it has also been modified for full-auto fire.

Appearances
Autumn appears only in Fallout 3.
