Underground Refinery

Heroes War: Counterattack has various modes for players to take part in, usually providing useful rewards. Some such modes include PvP, Boss Runs, Daily Battles, and more. The Underground Refinery is one such mode where players have to go through several battles and floors to collect various rewards. In this page, we’ll discuss this special dungeon and what you need to do to clear it.

The Underground Refinery is unlocked once you have cleared Chapter 6 of the main story. Once unlocked, you can access this dungeon from the main screen/lobby. To enter, you’ll need the Underground Refinery Ticket. 3 UR Tickets will be recharged every day at midnight, as part of the game’s daily reset.

The Underground Refinery has 50 basement floors. Every time you clear a basement, you’ll earn rewards. Tickets are consumed only when you successfully clear a floor. You’ll also earn UR Points that can be used at the Points Shop for rewards such as Exclusive EQ Pieces, Adamant, Steel, Module, and Compound Powder.

1. You can also check which mercenaries were used to clear each floor. You can use that info to adjust your team composition and which mercenaries to bring.

2. A Refining Machine will be installed every 10 floors. Once installed, you’ll be able to use the Refining function. This allows you to exchange unused Refinery Tickets for Refinery Points. It’s recommended to use this function when you’re stuck on a certain floor or if you have cleared all 50 floors. The more refining machines you have, the more RP you can earn whenever you use the refining function.

3. You can check the strategy of the bosses that appear on every 5th and 10th floors. Mid-bosses appear every 5th floor, while the main boss, Roxanne, appears every 10th floor (10F, 20F, 30F, and so on).
