Difficulty

Terra Invicta has four difficulty levels - Cinematic, Normal, Veteran, and Brutal. These difficulties impact a wide range of game mechanics, especially related to alien strength and behavior.

Non-Alien-Related

Value	Cinematic	Normal	Veteran	Brutal
Player modifier to contested missions	+3	0	-1	-2
AI spaceship build costs	x1	x1	x0.75	x0.5
Min ideological distance for AI envy	2.5	1.8	1.2	None

AI factions will also generally invest more of their research into global technologies at lower difficulties, and more into faction projects on higher difficulties.

Alien-Related

All alien-related effects are inverted if the player is playing as The Servants. A Servant game is easier if the aliens are stronger, so the same increases to alien strength that other factions would experience on Brutal difficulty are appropriate to Cinematic difficulty in a Servant game.

Importantly, the above is not true for The Protectorate. A Protectorate game will have a stronger alien faction on Brutal difficulty and a weaker alien faction on Cinematic, just like the anti-alien factions do.
