This is a 2D fighting game in which players engage in one-on-one battles against super-powered characters. Players punch, kick, and use various weapons (e.g., blades, knives, firearms) to drain opponents’ life meters. Characters can also perform special attacks that result in fiery blasts and large explosions. The game contains some suggestive material: female characters depicted in revealing outfits with large amounts of cleavage; dialogue that states, “Since I have a whip, I should probably have a sexier catchphrase. Talking like an S&M queen is really hard.” The words “sh*t” and “a*shole” appear in the dialogue.
Under Night In-Birth Exe:Late[st] is available right now in the North American region. If you are interested, you can preorder the game with this link on Amazon.
