Infected Metro

The Infected Metro is a gauntlet-styled gamemode where players have to progress through a set of stages in rapid succession, aiming to achieve the lowest time possible for supplies. It takes place in an abandoned metro system.

It can be accessed after a player has accumulated 90 Stars. It is found in the Stage Select menu.

Gameplay

Screenshot of a Metro run

Players must select a Station from the selection screen. No resources are required to start. Each Station has three stages that must be beaten one after another. The player must fight the set onscreen amount of enemies and successfully kill them all. A counter on the top right will track the required kills. Once that is done, a player will move onto the next part. If the bus is destroyed, the player will only have to restart the current stage, not the entire Station. There is no penalty for losing besides restarting. All enemies are in set positions, and will not change their position upon restarting the stage. This makes replays predictable.

After every stage ends, the player will have their courage and rage reset, as though it were a completely new level. During a stage, additional enemies than the ones normally onscreen will appear from the right side of the stage. These enemies are not required to be killed, though most of the time it will be necessary should they stand in the way of required targets.

If a pre-placed enemy can produce more enemies (I.E. Egg, Necromancer, and Sapper), any enemies spawned from them must also be eliminated. Likewise, threats like Undead and Sergeant can only be removed from play by exhausting their revives or burning them to death. Marauders are exempt from this. As long as all marauders are killed, a stage can progress regardless if they manage to turn after death or not.

In order to play, a set deck will need to be selected. Starting at Station 5, players will be required to bring a second deck into battle. Each stage from now on will have a second "part" that requires a second deck. Neither deck can share units, so each deck must have wholly unique units. There is no option to switch decks after starting a Station, so strategy must be utilized for which units to bring.

All units gain an AI upgrade to look behind themselves incase an enemy gets behind them. They will then attempt to kill them before facing forward again. Units will also stand idle if no zombies are alive or present to kill.

Each stage has a set of rewards, consisting of Power Points and Buffs. The run can be quit at any time, and stars will be given based on the stages completed. However, the run will not be considered finished and the rewards for the selected stage will not be earned.

List of Stations

The Infected Metro has 8 set Stations. Every Station has rewards for completing each stage, consisting of Power Points and Buffs. These rewards can only be claimed once per completion.

Additionally, each station will have a set of objectives to complete, if completed the player will be rewarded with a star. These stars go towards a counter for each station, with a goal post at 3, 6 and 9 stars respectively with increasing rewards. The star rewards are always as follows:

• 3 Stars - 100 Coins and 5 Cash
• 5 Stars - 150 Coins and 5 Cash
• 9 Stars - 300 Coins and 5 Cash

There is also a leaderboard for the quickest time to complete Station 12, with the following awards given to players:

• Top 100 - Exclusive Metro Rank, Shuttle Bus Paint
• Top 200 - 3,000 Coins

If a player has already received the top 100 rewards, it will be instead the following:

• Top 100 - 5,000 Coins, 5 Red Keys

Ranks

Ranks are small icons that can be seen next to every player's nickname. They indicate how many times the player has managed to stay in top 100. These ranks are not only displayed in the Metro's leaderboard but in the player's event leaderboard scores and missions deck as well.

Strategy

• Because of how fire damage can stack, Flamethrower, Red Barrel, Molotov, and Carlos (with his Special Ability unlocked) can all significantly contribute to overall DPS if used correctly.

• Shotgunners are great for spread damage and taking down waves, especially Farmer and Lester.

• Fury and Extra Courage are both useful for speeding things up.

• For stages that include Marauders, always bring bullet-resistant units to ward off their ranged weapons.

• HRoF units such as Carlos or Sonya are essential for DPS.

• The Police Team Power can provide a much needed ammo boost to many ranged units. As such, Agents with their Special Ability unlocked can be useful to save a slot in a deck.

• Ranger's Special Ability can easily knock vulnerable enemies away to make space.

• Most support items' preparation timers are simply too long and can be outright unusable, even with the 2/2 Jailers Team Power. But if the Jailers Team Power and the Energy Drink item may come to play, it significantly increases the rate of time, reducing the need to wait even more.

• Dr. Norman and Nitrogen can be used to dramatically slow enemies.

• Builder Abby with Fury and the Hunter items can mow down many enemies that aren't resistant to bullets. Reversely, using Tactical items can help shred down enemies that do.

• Drone can group enemies together, making them easier to target.

• Using Builders Team Power 2/5 has a 10% chance for an extra builder to spawn and 2% chance (because of the current amount of Builders skins in the game) for one of the builders to be Builder Abby or Mechanic, which are the strongest options.
  • Using this can lead to achieve times under 150 seconds and lower.

Trivia

• Infected Metro is the only area where two decks are used at once.
• The Infected Metro badge is the second unique player badge added, the other being Skirmish tiers.
• Infected Metro spawns enemies slightly different than normal missions, this causes zombies to not attack Marauders.
