Princess Rescue

Screenshot of the event.

Princess Rescue is an endless escort mission.

The event takes place in a tightly packed (but surprisingly well-lit) street alley with boarded-up stores and apartment buildings.

The main goal is to escort women fleeing from the zombies by letting them enter the bus. To hold zombies back, players must use several different rage abilities. The event consists of the same waves appearing in a set order, and then repeating again until the bus is destroyed.

What makes this event unique compared to the others is the preset combination of rage abilities players have to use in order to prevent zombies from reaching the bus and killing them. As courage and regular human units are disabled for the event mission, it is up to the player's ability to use their stationary units conservatively and effectively for the most chance of success and most amount of women saved.

Preset units for this event are Empty Barrel, Red Barrel, Molotov, Nitrogen, Turret and Drone. Bill does not have access to his LMG when the rage meter is full, and is instead given a grenade throw ability. All stationary units have the same level equal to that of the player's unit collection. If the player has not yet unlocked one of the listed units they won't be able to use them. The grenade throw deals 50 damage and is always at level 12.

Due to the nature of this event and the preset units for it, Energy Drink is the only buff that can be used.

One run of Princess Rescue may only last for a maximum of 6 minutes.

Enemies

Enemies will appear in small waves, with each wave containing higher level enemies. The level of the enemies will increase on based on the difficulty. Below is a table containing all of the enemies present, for each difficulty. The difficulty dynamically increases with each goal post reached, staying at the same wave.

Trivia

• Princess, who was introduced with this event, is the first ever neutral entity. This is done by classifying her as a marauder that rage abilities do not target directly. Outside of normal gameplay, if Princess is spawned in the presence of other human units, they will attack her.
• Grenadier's grenade throw was reworked and introduced as an additional ability for Bill in this event.
• During the day of its introduction, the event's page was glitched and had code name shown instead of proper title. Due to this, during the first few days, it was referred to as "Rage Event", likely stemming from the fact that only damaging rage abilities could be used to fight enemies.
• Drone is the only unit ever to be added as usable to the event.
