Halloween Event

Screenshot of the event.

Halloween Event is an annual event that is set near Halloween for 14 days. This year's Halloween Event lasted from October 23rd till November 7th.

The main goal is to kill enemies in a unique game mode. Players can also collect pumpkins by manually detonating pumpkin bombs. If any pumpkins remain after all enemies are killed, they will be automatically collected. Collecting pumpkins allows players to exchange them for a unique, event-exclusive prize, the "Halloween Case" at 20 pumpkins each at the Military Kit Shop.

The event is split across 14 days, with each event day lasting in 23 hours and 50 minutes with a buffer of 10 minutes before the next day. Each day will reset the leaderboards, rewards, and the amount of pumpkins that can be collected during gameplay.

Event Gameplay

What makes this event unique compared to the others is the waves system and "process of elimination" gameplay style. Players are tasked with protecting a new vehicle, the van, by using every unit they currently possess. Players must use a 3x3 field grid, functioning close to the one used for Skirmish where players position their units. Similarly, players must strategically position their units down in one of these tiles. The player always starts with 100 courage points. Rage always starts empty and must be earned by killing enemies. Once a wave is finished, players earn 5 courage points (and 10 on certain waves). Players can get additional courage by collecting courage packs randomly dropped during a wave, from Extra Courage buff, and from Generator. In rare cases, an enemy may drop a courage pack.

Every unit can only be placed on the grid once. After they are placed down and enter battle, they will not return to the deck and will fight for every round until they die. Once they are dead, they are gone for the rest of the attempt. Before the next wave, players can strategically move the units around to position them in a more favorable spot, whether to protect an important unit or bring them closer to the action. If the grid is full, i.e., nine separate units have been placed down on the grid, players will be unable to move any of the units until at least one of them dies. Each rage ability can only be used once in one wave only, but can be placed anywhere on the battlefield outside of the grid. Rage abilities destroyed by being run over by the van will not cause any damage to it. Once every one of the player's units are used, the van gets left on its own, allowing enemies to easily attack it and end the current attempt. Rage abilities alone automatically makes the van move forward.

Unlike in the main game, enemies in this event do not pause in between steps and will continue moving towards the van save for marauders wielding a ranged weapon. Only units and rage abilities will temporarily stall them so it's important that units are placed accordingly to avoid them (mainly ranged units) gathering together and face an enemy point blank with a dangerous ability or high damage.

Some waves have pumpkin bombs in them. Most early waves usually contain one, few, or no pumpkins. Some later waves will contain numerous pumpkins. A pumpkin bomb can be manually detonated to inflict damage to its nearby enemies similarly to Red Barrel minus the fire pool. It's highly recommended exploding these pumpkin bombs as not only they can kill or weaken enemies, but also prevent units (mostly fast melee units) from moving past a nearby pumpkin bomb as it explodes. Pumpkin bombs are also capable of harming units as well much like Red Barrel and detonating them early prevents the risk of unnecessary damage. Pumpkin bombs cease to appear once players have collected the maximum amount (160 exactly).

Due to the nature of this event and its gameplay, Fury and Extra Courage are the only buffs that can be used. As mentioned, Extra Courage buff is one of the other ways to get more courage for units. Fury buff's damage-boosting effects can only be applied for the fight it is used in as it will disappear upon entering the next one. However, it as well as Extra Courage buff can be used in several battles throughout the player's attempt.

During the event, the player can go through 89 preset waves. After completing the 89th wave, this particular wave will repeat for the next 11 waves. Upon reaching the 101th wave, the amount of enemies will drastically increase. These waves will repeat until the van is inevitably destroyed.

It is worth mentioning that Carol and Private Rodriguez get a similar buff to the one they have on Skirmish; their abilities starting range is infinite instead of being only activated when at a short distance from their target.

What's more, there is a new stage mechanic in the 2023 Halloween event: After completing the 33th wave, player's units lose 150 valor per wave and this is stackable. It means most of your units will be feared after completing around 10-20 waves. Feared units have longer reaction time and less agression to enemies which is a deadly threat in following waves.

Trivia

• There is a multitude of bugs related to the Halloween Event:
  • When the van encounters Fat Zombie and no units are there to kill it, the van will move but when it would supposedly ram into Fat Zombie, both it and the van will just idle, softlocking the game and forcing players to give up.
  • When Glenn gets knocked down in a previous round, he may appear from (or on) the right side of the battlefield and running in the direction of the enemies. Unlike most bugs with the event, this one is quite helpful as he will essentially backstab enemies and force higher health targets to turn around to deal with him. There is also a chance for him to appear in the area near the grid but will be unable to be moved to a different position by the player.
  • Carol will usually be able to deliver a critical hit at the very start before the wave begins. However, she will still be on the grid, safe from harm.
  • There is a bug with Agents. Specifically, the 2nd agent will randomly appear ahead of the grid before being placed back in his spot on the grid. This can sometimes lead to him dealing or taking damage the moment before the wave is suppose to start. In a few cases, he may even stay in that spot out of his position on the grid, likely leading to a swift death.
  • When using rage abilities like Generator or Turret in combination with or without units and them getting destroyed, the van will sometimes freeze and stay in place, easily leading to a loss due to enemies hitting the truck.
  • Enemies moving directly in front of the destroyed van will still get knocked back or die. Obviously, these kills will not be added to the final score.
  • Sapper and Armored Skeleton who have a chance to degrade when killed, Crazy who turns into Fast Zombie on death, and Putrid who releases three Rottens when killed will be ignored by units should they be killed last. Unless directly in front of them, units will not attempt to kill them, meaning the van could take unnecessary and unfairly unavoidable damage in the transition to the next wave.
  • New units and those already placed on the grid cannot move into grid squares that are currently occupied by a courage pack.
  • Units that die from fire or poison moments before the next wave is suppose to start will be unable to be moved. However, the grid square that they were on will still be considered occupied, preventing other units to be placed until the next wave.
  • If Nancy split second revives a unit in the event, the unit will be revived and remain in their previous position while their spot is opened in the grid allowing another unit to be placed where they once occupied, resulting in the ability for more than nine units to be placed.
    • The revived unit however will not respawn in the grid, instead in the position they were in the previous wave meaning they can be placed right next to zombies between waves.

• When the new Halloween Event was introduced, players who had any pumpkins leftover would have them converted into money at a rate of 10 pumpkins for 1 money. However, this money conversion feature was not repeated the following year.
