Dev Diary: End-game Maps

In the upcoming 0.9.11 patch, we’re revamping Path of Exile’s end-game to introduce a new system known as Maps. Players in high level areas can find Map items that allow them to travel to random end-game areas featuring bosses, awesome equipment and more Maps.

Maps can drop as normal, magic, rare or unique with higher rarity Maps yielding more items. Using a Map item opens six portals to the area, which can each only be used once. Like most other items in Path of Exile, Maps have mods that change their risks and rewards. Map mods can affect the size or complexity of the level, monster packs, monster properties or even alter characters while in the level. Players can modify Maps themselves using their currency items. For example, you can use an Orb of Transmutation to turn a normal Map into a magic Map, or use an Orb of Alteration to reroll its mods.

We’re sure the result is a highly replayable, challenging and varied end-game that will make Path of Exile fun for a long time to come. This development diary describes the design process of this system and how it works. Узнать больше.

Having Maps as physical items that have to be found or traded for is the backbone of having a very replayable end-game. There are already plenty of static tasks that high level players can do in Path of Exile, such as boss runs or farming exploitable content. Map areas have a large range of random properties and rewards, so representing them as tradeable items adds a whole new dimension to both the game economy and opportunities available for high level players.

How Maps Work

In 0.9.11 there is no Maelstrom of Chaos. When you complete the (temporary) end of the Beta by finishing Act Two of Merciless difficulty, you will instead be given a waypoint to the Eternal Laboratory. This is an area that you will eventually find in Act Three, but we’re granting access to a temporary equivalent earlier so that Maps can be tested.

When players enter their Map, they appear near a portal at the beginning. If they use a Portal scroll while in the area, it moves the starting portal to where they are standing. This means that when they re-enter the Map via the Eternal Laboratory (where they consume one of the available portals), they will be at the new portal location, as opposed to the initial portal location. This is convenient for bringing friends in to help with the challenges of the area.

Base Types

Like any other type of item, a Map has a base type. Each type represents a world area, such as a Dried Lake or Crypt. The base type also has a level, which is the monster/chest level of the area that will be spawned. In the first iteration of this system, there are 45 such world areas laid out between levels 60 and 69 inclusive (with a skew towards lower level areas currently). At least in this initial Beta implementation, tilesets are occasionally repeated at higher levels.

Where Maps Come From

You can find Maps by playing in high level areas. In 0.9.11, they drop from level 60+ monsters (i.e. the end of Merciless Act Two), so players who do runs of the Act Two boss will find level 60 Maps occasionally. Maps can also be dropped by any monsters or chests inside a Map, as those monsters are all level 60 or above. Once we add Act Three (and remove the fourth difficulty level), we will change the Map levels so that they drop around the level of the Act Three boss in the final difficulty.

Just like the rest of the game, most of the monsters in a Map level are normal monsters that are the level of the area. Magic and Rare monsters are one and two levels higher respectively, which means that they can drop slightly higher level Maps. For example, if you’re playing a level 62 Map, it’s possible to find level 60-62 Maps from normal monsters and level 60-64 Maps from rare monsters.

Map Drops

Maps will not always yield another Map to play. On average, players will not have a constant supply of Maps unless they trade for more or do end-game boss runs to try to find another when they run out. This is the same philosophy as any other end-game item (players are always pretty low on 200% damage weapons), and is necessary to help keep Maps rewarding and valuable.

We want it to be difficult to obtain the higher tiers of Maps. If players complete several Maps successfully and are lucky with Map drops, they can obtain Maps that are potentially too high level for them to complete. It’s reasonable for them to chose to trade these Maps to more advanced players who are able to handle that content.

Like the rest of the game, having multiple players in an area increases the drop rate of items and the experience that monsters yield (while making them more challenging). Under the new system, there is an exception: the drop rate of the Map items themselves is not increased by the additional players (all other items drops in the area are still increased, of course). A Map has the same chance of yielding other Maps regardless of how many players are in it. This is because a single Map item can be used by a whole party, unlike other items that can only be used by one player. The item quantity bonus that a Map has (due to its Mods) will affect the drop rate of Map items within that Map.

We plan to use Unique Maps as a way of creating interesting areas that might be confusing or overplayed if they were in the core game. The words “Crazy Teleporter Level” and “Temple of Kuduku” were uttered in a Map design session earlier this week.

History of Path of Exile’s End-Game

Action RPGs typically have three difficulty levels. The player plays through the game several times using the same character, with the challenge ramping up each time. Right back at the start of the project, we thought it would be a great idea to add a fourth difficulty level that was really challenging so that players would have something to aim to beat.

When we tested this, we found that players reacted really badly to a sudden brick wall of difficult content that they were unable to progress in. We tried changing it to a steady ramp of difficulty, but then players found isolated areas where the monster AI was more abusable and farmed those with specific builds to get rewards with little risk.

When trying to solve this, we realised that the fourth difficulty level was only necessary until we added Act Three, at which point we’d reduce it back to three difficulty levels so that we’re not forcing the player to play through the same static content four times back-to-back. Our temporary solution, a month or so before entering Closed Beta last year, was to introduce the Maelstrom of Chaos areas. These were a sequence of random areas (using tilesets from all over the game) with completely random monster packs. Players gained access to it when they finished the final difficulty and could play through a series of levels that gradually ramped in difficulty.

The Maelstrom helped the situation, but players would still travel to areas that were too hard for them and complain that they weren’t able to kill monsters. We eventually flattened all the Maelstrom areas to be the same level, just ramping in density of bosses. By that time we had decided we needed a new, better mechanic for access to end-game areas. Maps will replace the Maelstrom in 0.9.11.

Variable Difficulty

An expected consequence of the amount of customisation that Path of Exile offers is that characters can differ in power by large amounts. Players abusing whatever the current broken skill is with a clever synergistic passive build, godly rare items and high-quality Skill Gems are able to handle triple the challenge of other players.

Our end-game has to cater to both groups of players. Both regular and power players need to be challenged in different ways, so that they feel the need to continue to improve their characters. Our Map system allows players to pick the difficulty that they encounter. As you’ve seen in this article, players can create and obtain harder versions of Maps that offer more challenges and more rewards.

Non-Map End Game

Of course, Maps aren’t the only thing to do in Path of Exile’s end-game. There are plenty of other exciting options for high level players:

We’re really pleased with the new Map system. In testing it has been rewarding to play and adds more replayability and strategy to the end game. We’re eager to hear your feedback after you’ve had a chance to play it in 0.9.11. If you haven’t created a Path of Exile account yet, please sign up here.
