3 mechanics, as Middle-earth: Shadow of Mordor does them

core · 3

control & automation

Direct avatar control

The player controls Talion directly in third-person combat, stealth, and traversal.

agents & behavior

Memories and thoughts

An orc that survives an encounter with Talion remembers it, and its dialogue refers back to the earlier fight when it taunts the player.

world generation

Procedural characters

Orc captains and warchiefs are generated with names, strengths, weaknesses, and personalities that the player exploits.

core loop

study Sauron's army on the Nemesis screen -> hunt a captain or warchief, exploiting its strengths and weaknesses -> kill, brand, or flee from it -> survivors and killers of Talion are promoted and remember the encounter -> turn branded captains against their warchiefs to take over the army

design notes

A boundary case: the core loop is authored third-person combat and stealth, and the record is included for the Nemesis system. Sauron's army is a ranked hierarchy of warchiefs and the captains under them, each a procedurally generated orc with a name, strengths, weaknesses, and personality. The hierarchy updates from the outcomes of the player's encounters rather than from a script: an orc that survives a fight or kills Talion is promoted and gains power, and its later taunts refer back to the earlier encounter. Talion cannot die permanently, so each player death feeds the hierarchy instead of ending the run. Infighting between orcs can be triggered, and in the second half branded captains serve Talion, so the player reorganizes the same hierarchy from inside. No mechanic in the vocabulary owns a persistent, ranked roster of rivals whose standing changes with each encounter, so the run files a new-mechanic proposal rather than force-fitting career-ladder. Warner Bros. patented the system, and only the sequel, Shadow of War, has used it.
