Who I'm Following
TOKYO NECRO SUICIDE MISSION | Japanese
I really enjoyed this game on browser (dmm.com) when I played it. I can't say if the mobile will be as good, but I can recommend it at the beginning. Good rates for waifu collection, good gameplay, excellent story (for a mobile game at least), great waifus of all kinds. As f2p I was able to get almost all the characters I wanted and even max them out without issue. And I wanted a lot of the 5*s they came out with.
Here's why I quit playing: You need 30 copies of each 5* weapon max its stats. And you need 10 weapons for each character. Event weapons are fine (you're not getting them maxed out without spending, though) but not as good as the gacha weapons, and you'll need those gacha weapons maxed out for raid bosses and challenge quests. And you'll need to beat raid bosses and challenge quests to max out more weapons.
It's not something that really affects you at the first few events, but it gets worse each event until I, someone who played from day 1 and spent a lot of time on the game, couldn't even 3* the lowest of the challenge events because I couldn't kill fast enough with ~10 upgrades to each weapon.
If you're willing to pay only a little I'd recommend only spending on weapon gachas to max out a few weapons early on. If you're not spending, spend time with your waifus but know that you won't make it a year in this game.
P.S. there are h-scenes only if you play on the R-18 side of dmm, so if that matters to you find the browser version.
Excellent presentation and there are many interesting heroes. The story mode looks very promising. Hope to see it in English.
