As much as the guro interest me, they could fully flesh this game out and remove (or lock) it with some major overhaul to the sexing. Too bland in the first game despite something refreshing, usually this stuff is 2D and it was kinda neat seeing it in 3D... Albeit a bit choppy.
The basic zombies should at least have a double team.
Basic x1, x2, x3, with a Bukkake Game Over (x1 and x2 can have any variation, A + M, M + P, P + A)
Basic + Crawler (the one that spits acid, M + A/P (respectively))
Basic + Rager (maybe, they don't really care for Basic so lore wise, it's the "Alpha" taking control)
Crawler (A, M, P)
Rager x1, x2, x3 (imagine a x3, god damn rip, {as stated with Basic})
Worm x1, x2 (think this
, "Eat Me Please", a solid fucking read)
Bloater... I honestly don't see where it's going, and I've played an older version so Idk anything that it does if they changed it. All I know, he just stands there til it's too late then GO, however... x1, x2 (again, imagine this one too, M + A/P)
Ofc this is a lot to add, but man, if you got the funds and people, you could really make a killer fucking porn game. A shame it doesn't happen in a true 3D game (games not really of this nature, but creatures in general, not vanilla shit) all that much.
