The similarities to FTL include, Sector/Zone navigation. I've made it only to sector 3, no idea how many until "the boss". There are currently 3 ships, I have only flown the interceptor, they added a scout and gunship. Weapon, Item, Resource drops are random and the areas have randomized aspects. I've seen Traders, Repair Vessels, Wrecks, Giant asteroids with shit inside. Random space station/shipwrecks. If you fly to the "edge" of an area you take dmg and will die.
I've seen three factions besides myself. The one that begins neutral is like a Space Corp, you can go pirate on them, but I think they become hostile for the rest of the game. There are then generic outlaws, and an alien faction that is aggressive as well. Each group has their own ships, although I haven't seen much yet. The alien faction sometimes send interceptors to the area you are in, and so far I just run away from those (after dying a couple times).
When you die, the amount of currency you had can be spent on a perk tree. There are generic perks as well as ship specific perks that persist. This progression gives you various legs up/performance advantage.
There is 3 difficulties Easy/Normal/Hard - there is an explanation of what is changed in Easy/Hard when chosen. I have only played on normal.
There are 15 resources that go into this crafting/blue print /upgrade system. The quantity and drops are clearly randomized. It is almost too much at the start and my explanation is weak, but its quite robust. How many special items to use, which include sensor scans, shield drones, attack drones, capital class torpedos, homing missiles. Much ammo can be crafted if you've got the right drops and discovered the blueprint. I'm 9 deaths in and learning.
I think the keyboard controls+mouse are superior to the default gamepad controls. I have played the entire game with a custom config on my steam controller where I just mapped the keyboard/mouse to bypass their bad gamepad setup.
Its quite brutal, its gonna take some time to get places I think. But early impressions are strong. If you love the idea of FTL meets an arcade space shooter, this game is for you. It is almost quite literally that.
Edit: I'm pretty addicted.
