While playing Xenonauts 1 - I have always only used "classic" (automatic) combat. The reason is that aerial battles are too monotonous and the player rarely has losses. No critical hits. The battle tactics are always the same. Which is not surprising: the battle conditions (environment) do not change at all. Also: there are no random factors in combat. I would suggest adding the following to air combat:   - Night-Day. The accuracy of the rockets in the sun is lower.
