Very much a full on gacha game with many systems copied from other popular ones. There's a good variety of play here and the gacha aspects don't seem like a huge deal. I'm currently time gated on progression because chapters unlock through daily bounty/challenge rewards, so I haven't had an opportunity to test everything.
Characters have banners but that's it, no signature weapons from pulls. Guarantee is at 60 and there's a knockout system that shows exactly what your set of 10 pulls will entail.
I set it up on Bluestacks so I could use mouse and keyboard and that was a huge step up. Always being in first person makes it feel much more like Destiny. I don't really understand why they are faking like a PC port wont eventually come out. Even in some of the tutorial screens you see things like "Press G to Finish" in the explanation videos, lol.
