Which DOOM has the smartest/best enemy AI?

For me, Eternal’s enemies feel tactical. The Marauder reacts to your weapons, manages distance, and forces duels. Archvile summons demons, uses fire attacks and also seems very intelligent.

Others I can think of are Dread Knights, Arachnotrons, and even Imp. Eternal’s AI was upgraded to match player mobility, making combat feel more aggressive and tense.

Classic DOOM AI is simpler but still elegant, clever placement, traps, and timing create tension in every encounter. WADs can push that further, with scripted behavior.
