The Citadel is a hardcore old-school first-person shooter in which you will find numerous enemies and bosses, a sea of meat and blood, a variety of weapons. The events of the game take place in a kind of Citadel, in which you just go along with the main character. It is full of monsters, various nasty creatures, drones, armed to the teeth, and more, and you will have to fight with them, using everything at your disposal. And believe me, it will be very, very difficult. This is a typical old-school 2D first-person shooter, based solely on the most simple and well-known processes and mechanics. You will go through various levels, exploring the environment and fighting monsters, fighting bosses, improving weapons and looking for new guns, and survive in every possible way.
