Metro 2033 is based on the popular Metro 2033 universe created by Russian writer and journalist Dmitry Glukhovsky. After the nuclear strike, thousands of survivors have found refuge in the Moscow underground, the biggest shelter in the world. In the stations and tunnels deep below the surface a new civilization emerges.
Each faction has a hero at its disposal. Heroes can travel the underground, gain quests and equipment that increases their abilities, fight opponents heroes, attack stations, and so on. The army of a faction can also attack stations, and usually with better chances to win, but it can target only adjacent stations. Stations under factions control produce resources, pigs, ammo and mushrooms, that are used to capture new stations, strenghten the army, buy equipment and obtain quests. The production of resources and other game events are determined by a special sequence. This sequence tells what will happen each round, production of certain recources, a vote for a new law, or a sudden attack from the dark that must be repelled.
Players can attack stations with their armies or their heroes. Both have strength that may be increased by hiring new troops or buying useful equipment. When attacking a neutral station, the army/hero fights a random threat from the special deck and has to beat its strength. When attacking an opponent, the attacker confronts his army or hero. In battles between players a special set of combat cards is used; these cards give various bonuses to strength depending on the card chosen by the opponent, so the goal is to deduce which combat card will be used by the other side.
