The Last Stand: Union City

The Last Stand: Union City is a zombie survival game set in the titular Union City. The character-created protagonist is returning home from work, outside the city, when they unknowingly crash into a zombie. Although they hadn't been aware of the zombie apocalypse, they must now fight their way through the city, collecting resources and helping other survivors along the way, with the ultimate goal of reaching their husband (if the protagonist is female) or wife (if the protagonist is male).

The basic gameplay strays away from its predecessors' tower defense-esque gameplay, instead opting for a 2D side-scroller as the player shoots and stabs their way through zombies. The game still preserves an emphasis on scavenging, allowing the player to explore numerous buildings that are optional yet can contain helpful items. These include weapons (from pistols to crossbows), medicine, food, clothes, armor, and, most commonly, useless junk. The game also features RPG elements: by killing zombies, completing quests, or obtaining achievements, the player also gains experience points that allow the player to level up and improve their abilities.

The player has five main attributes that each govern a set of skills. Strength influences carrying weight and the damage from melee weapons, Precision influences accuracy and reload times for firearms, Intellect is a catch-all for non-combative skills such as lockpicking and scavenging, Endurance influences their stamina and defense against attacks, and Luck is the exception, having no skills itself but influencing nearly every other attribute or skill (such as increasing the chance of critical hits or lowering the chance of finding junk).

There are two basic game modes: Run and Gun, where ammo and weapons are more plentiful, and Survivor, which not only decreases the amount of discoverable ammo but also introduces a food and sleep system. In Survivor mode, the player is required to regularly eat food and sleep, otherwise their stats are significantly decreased and, if alone for too long, they die.

A premium DLC pack, Survival Kit, added a new location alongside several weapons and game modes; it was later included with the base game, although all of its content still has the [Premium] affix.
