A mere eight days after I expressed myself in no uncertain terms, a video is released for the upcoming Tekken Tag Tournament 2 allaying my ungrounded fears! Apparently a swimsuit DLC is being granted, modeled here by Heihachi and Kazuya . . .
. . . and Lee and Ganryu.
The crux is every character gets themselves a free 'swimsuit' costume. Although females are the prime selling point here, it was revealed in the video that this goes for every character, males and animals(!!) included.
Shortly afterwards, there was bemoaning among certain segments of the fandom that the male costumes show more skin than the females' do. XD
Heihachi in particular seems to enjoy showing off.
This DLC comes free with pre-order, and otherwise becomes available three months after release. :0
