this one isn't really 3D but it's a looter-shooter at it's goddamn core, SAS:4, top-down view, pve, and it's pretty addictive. the graphics are decent but it has good replayability.
There's also this other one, The Walking Zombie 2 , it's 1st person, kinda lootershooter/rpg/pve inbetween. it's pretty fun, though the only downside i've encountered was the energy system, though you can play a good 1 to 2 hours before it runs out.

It's this game. I can confirm that Monster Island either uses screenshots from it or at least looks identical to it.

SAS Zombie Assault 4 - top down but has online co-op.
If you have friends that will play with you Ninslash, a 2d platformer arena shooter has a Zombie defense mode with bots that is fun.

Probably a good number of them migrated to the sequel.
