Evolve is one of the best games on XBOX ONE.
There are four players that act as good guys and the fifth player is a bad guy. Basically 4 alien monster hunters and 1 monster. The roles of the good guys are support, assault, medic and trapper. The monster just plays a monster, which is player five.
Styles of maps on the game are jungles, indusustrials etc. Both vegetation and man made are your obstacle courses. Try to remember the maps as soon as possible! If you don't then you won't know where the monster might evolve. Be aware that the monster can evolve anywhere and into smaller creatures, hence the name EVOLVE.
Anyways I don't want to spoil the game for you but it's quiet the treat! If you want to know a detailed view of it message me and I could talk you through parts of the game. Maybe your stuck with the Kraken? I can guide you through it, let me know thanks!
