Midtown

Midtown is unlocked after clearing Stage 2-9. Your first session will be at a beginner's difficulty level, regardless of your user level. Subsequent sessions will increase in difficulty to suit your experience.

Midtown is played in 48-hour sessions. While you are in Midtown, look near the top of the screen to see how long is left in the current session. That is how long you have to try to meet the Midtown objectives and clear all three areas to earn all the rewards.

At the end of each Midtown session, there is a full reset; the tactics you collect and wandering heroes you rescue in any Midtown session are only available during that session and will not persist when the next session begins.

Progressing through Midtown

When you enter Midtown for the first time during a session, you start at the beginning of Area 1. To progress through each area, you will need to clear tiles to fill your objective gauge to 100%. Each action you take earns you progress: battles reward you with +10% and all other tile actions reward you with +5%.

For non-battle tiles, accepting or declining the action will reward you +5%. Declining the action is a final decision per tile; while you may encounter other similar items as you progress and unlock more tiles, you cannot change your mind about using the item or action you initially refused. You can X out of a tile if you are not ready to choose whether to accept or decline, but that does not earn the progress reward or unlock the adjacent tiles.

You will not be able to fight the Boss zombie and clear the area until your objective gauge is at 100%. Once the gauge reaches 100%, there is no way to continue exploring tiles and collecting items; proceeding to the Boss battle will be the only remaining move you can make in the area.

Battles

There are four types of battles in Midtown:

Appearance	Battle Type	Rewards
	Normal Battle	+10% objective, resources, and a Rare or Epic Tactic
	Elite Battle	+10% objective, resources, and an Epic or Unique Tactic
	Boss Battle	Resources and a Unique Tactic
	Berserker Hero	+5% objective and that hero joins your squad

Heroes

As you travel through Midtown, you will encounter tiles populated with wandering heroes. You can choose to rescue one hero per tile. Rescued heroes are then available for use in Midtown battles for the remainder of the current Midtown session. This is a great way to see what some other heroes can do! These wandering heroes may also include heroes you already own, but at higher levels. That is an opportunity to see how powerful they are on their way to becoming.

When you encounter lost survivors, you have the choice to rescue or ignore. To rescue a survivor, choose one of four equally strong heroes to add to your Midtown squad. Tap the magnifying glass icon to see the hero's details before choosing. Your rescued hero will be available to you in Midtown for the remainder of the current session.

At the start of a Midtown battle, build your squad with any combination of your own heroes, hired mercenaries, and the lost survivors and berserker heroes you have rescued during this session. 

	Heroes you have found in Midtown are marked with a blue pawn symbol at the bottom of their icon.
	Hired mercenaries have a yellow pawn symbol.

Once you reach Area 3, you will start to encounter berserker heroes. You can rescue berserker heroes, but they are unpredictable. To gain their loyalty, you must first defeat them in battle. Once you rescue a berserker hero, they will be available in Midtown for the remainder of the current session.

Heroes rescued in Midtown can only be used in Midtown and only during the session in which they were rescued. Rescuing heroes in Midtown is a great way to try out strong heroes you may not have played with before.

Health

In Midtown, heroes' HP carries over between battles. This means that if a hero gets injured or dies, they will remain injured or dead until healed or revived. There are three ways to heal your heroes.

	Medkit Medkits can be found on Midtown tiles. Use one to recover 50% HP for all living heroes. If you abandon it instead, the Medkit will disappear without healing your heroes. Whether you use or abandon it, your choice will add 5% to the progress gauge. You might choose to abandon a Medkit if you are using Midtown Tactics that buff heroes only at low HP.
	AED Kit (Automated External Defibrillator) Like Medkits, AED Kits are found on Midtown tiles. AED Kits will revive a fallen hero and restore their HP to 100%. If you use an AED Kit when all your heroes are alive, it will max out a random hero's HP. Using or abandoning the AED Kit will add 5% to your progress gauge.
	Elite Medkit Elite Medkits can be used at any time during Midtown, as long as you have some in your Inventory. You earn Elite Medkits by completing quests outside of Midtown. Elite Medkits will revive fallen heroes and fully restore the HP and SP of all heroes.

Tactics

After completing Normal, Elite, and Boss Battles, you get to choose from a random selection of three Tactics. Tactics are perks that will boost your heroes' stats and help your squad take down their enemies. Learn all about hero stats in Undead World: Hero Survival.

	A newly cleared battle tile reveals Tactics! There are Rare, Epic, and Unique Tactics to choose from. You cannot perform a new action on a different tile until you select a Tactic.
	Normal Battles most frequently offer a choice of three Rare Tactics. Occasionally, an Epic Tactic may appear.
	Elite Battles typically offer a choice of three Epic Tactics. Occasionally, you will be offered a Unique Tactic.
	After completing a Boss Battle, you will get to choose from three Unique Tactics.
	Tap the Tactics icon in the lower right to view all your active Tactics. This is useful for selecting new Tactics that will complement each other and for choosing your battle squad to take advantage of Tactic buffs. For instance, some Tactics buff only a certain faction of heroes; others increase in power based on how many heroes of a faction are on the squad.

Tactics are only available for the current session of Midtown. They do not apply to battles outside of Midtown or carry over into the next Midtown session.

Expert Mode

When you play in Expert Mode, you face teams of rival heroes rather than zombie foes. There is only one area in Expert Mode, but the battles are harder, so the rewards for finishing in Expert Mode will be no less than for completing all three areas in Normal Mode.
