Actually putting some time into it, it's not bad, but 1) I'm not buying a post-Kojima/Iga Konami game ever again. 2) the hoard mode (that is the only mode that the beta has) is pretty short and easy to S-rank if everyone knows what they're doing.
You mean it's easy to S-rank on Easy difficulty? Do tell more
No, normal or hard. Put the digger on Speed-up, spam the sledgehammer, win. All you need is four players doing that and putting self-firing turrets and maybe the stun traps down if need be.
2-players may struggle on Normal (just got a B on the mine because no materials to continue to hammer down enemies), but the game design is supposed to be based on 4, so...
