FPS games like CSGO

Depends on what you mean by games that look like CS:GO. Games like Soldier Front, Combat Arms, Zula, Black Squad, Standoff 2, Day of Defeat, etc. might resemble Counter Strike, but some of those titles are fairly old so if you mean shooter games in general, then Battlefield, Call of Duty, Apex Legends, Destiny 2, Rainbow 6, etc. can be worthwhile to check-out.
