A new mechanic has been added to the campaign mode which allows the player to solve puzzles (tsumego) in order to raise the fortification level of regions they have conquered.
Each puzzle solved will raise the fortification level by one, up to a maximum of ten, at which point the region is fully fortified and cannot be invaded.
Regions will periodically lose fortification levels after playing matches. When returning to the map screen, each region that lost a fortification level will briefly flash in a red outline.
Once a region reaches a fortification level of 0, the region is lost to an opposing nation.
Regions that have a fortification level of 2 or less will have a red warning outline around them until the level is increased or the region is lost to an opposing nation.
When hovering the mouse over a region, in addition to the board size and most recent match result being displayed, the fortification level is now also displayed.
The current difficulty level (AI type, AI level, handicap) of the campaign determines the difficulty level of the puzzles that are presented to the player.
There are currently ~1350 puzzles ranging through the various difficulty levels.
Puzzles are loaded in a random orientation, allowing them to flip horizontally, vertically, diagonally, and also change stone color.
A variety of puzzles are stored both locally on the player's PC as well as online via OGS. While not required to play puzzles, those that have an online connection will have access to a larger pool of puzzles, as they will not be restricted to only locally stored puzzles. The majority of the puzzles are stored offline however.
There is a new Steam stat and achievement for completing puzzles, which can be found within the Stats portion of the Extras menu.
Solving Puzzles:
Solving a puzzle without making any mistakes will award bonus resources to the player.
A button is available to display the correct move in a given position to the player. Using this method will however only allow the player to raise the fortification level up to a maximum of 7 of 10.
There are two different modes for solving a puzzle depending on the puzzle that is presented to the player:
There is a multiple choice mode, where each possible move is highlighted on the board, and it is up to the player to choose from the given moves.
The other mode simply shows the puzzle board position as-is with no highlighted moves, and it is up to the player to find the best move on their own. The majority of the puzzles fall into this category.
Campaign Tutorial:
A full tutorial has been added to walk through the different mechanics of the campaign mode.
The tutorial covers many aspects such as playing matches, abilities, resources, market exchange, reviews, fortifications, invasions, and more.
The tutorial can be accessed by clicking the Campaign button on the main menu and then clicking the Campaign Tutorial button.
Updates
The base resource value for the campaign mode has been slightly reduced to account for new resources that are able to be earned from fortification puzzles.
Campaign Invasions
Invasions can now be defended either by playing the remainder of the match from the starting position or by fully fortifying the region by raising the fortification level to 10.
If your regions are fully fortified, invasions can now occur in nearby regions to those that you've conquered. These invasions are optional to defend, as the player is not at risk of losing a region from their empire.
When clicking the invasion icon, instead of immediately loading directly into the match, a preview of the starting board position will be displayed, allowing the player to click the resume button to pick up the match at the starting position, defend the invasion through fortification, or ignore the invasion.
Fixes
Fixed an issue during review mode which was causing variations to not be displayed under some circumstances when using the AI Move Analysis feature.
Fixed an issue with the ko marker remaining displayed after loading a new file or tutorial.
Fixed an issue with the resource icon on the campaign map screen being able to be clicked when not intended.
Fixed an issue with the board recommendation icons from review being able to be clicked when not intended.
Fixed an issue playing online matches that were created on the Online Go Server (OGS) by creating a fork of a game in which the new board position starts with the white stones.
