Xenus is not another 3D action game with some elements of RPG. It is really both RPG and action. Killing is not the goal of the game.. Your goal is to find the sister, so you need to talk with many people to gather necessary information. And these people will not be always friendly to you. There are no predefined enemies in the game. There are a lot of characters but almost all of them are neutral to you at start. Actually, there are six sides in the game: officials, guerrilla, narco mafia, Indian, bandits, CIA. When you help to one of the side you inevitably spoil your relations with others. In the world of Xenus everything costs money.
