Back 4 Blood is the latest cooperative zombie-shooter from Turtle Rock Studios, and it brings some unique concepts to the table, including the Supply Lines system. Players must learn how to work through this system to earn the best items and buffs the game has to offer, a must for those trying to take on the most challenging encounters in the Back 4 Blood.
Supply Lines are where players spend the Supply Points earned to purchase new Cards for their Decks and cosmetics for characters and weaponry. Players earn Supply Points by playing Back 4 Blood's missions and even get bonus points for completing levels. Players can access Supply Lines with the in-game menu via the Supply Lines tab.
Supply Lines each have their focuses, so read the description of each Supply Line before purchasing an item. Players must also complete supply lines in order from start to finish. Players cannot skip entries in the Line. The higher the difficulty, the more Supply Points players can earn. Be warned that Veteran and Nightmare in Back 4 Blood are far less forgiving than Recruit can be.
