Looks like SH4 is on the backburner as of now.
Hopefully they'l get around to modding this game, unfortunately it just seems like most have jumped from SH3 to 5 or just stayed on 3 and never gave 4 a chance..
Anyway i support HAHD whatever engine they take ill probably end up playing it.
Hell i still have SH2 installed, might try modding that lol..
