As for today we have 5 paths, while the menu uses hexagonal pattern. Maybe we could use that space to add new things? My ideas: History of Jekotia (archeology) - new, ancient weapons and blimps Genetics/nanotechnology - buffs for infantry, squad skills? Quantum physics - some cool armors that based on RNG? This is pretty random, so I'd like to hear what do you think about this.
