To expand your headquarters, you need three raw materials: coins, wood, and stones.
You will get these resources during the course of your mission. Missions of the "standard" type are best suited for obtaining raw materials.
Treasury is a room that you can unlock at level 4 of experience. It enables the acquisition of coins; their volume depends on the level of improvement of this object.
After you reach level 12 you will unlock the Supply Room. This facility enables stone and wood to be extracted. This room can be upgraded so that your team can earn even more raw materials.
In this Resources tab you can buy raw materials:
- 35000 coins - 100 helix points,
- 10000 coins - 50 helix points,
- 25000 wood - 500 helix points,
- 10000 wood - 225 helix points,
- 3500 stones - 500 helix points,
- 1500 stones - 250 helix points,
