There are no tactical actions in the game like in SS/JA and other similar games (changing position for example), but if you hide behind a wall or behind a post, the opponent will not be able to attack you. Feature is an inanimate parameter in the game, created once for the entire game, but in the game there is a chemical and other things that can permanently change characteristics, as well as products can temporarily change characteristics (for example, for high PRS dialogues).
