Drakengard 3 is revealing its pre-order bonuses in tiers, and as of today the first tier is officially expired. It's too late to get the Japanese voice-over pack, but Square Enix has revealed the next pre-order bonus: a Nier costume pack.
According to a post from Square on the PlayStation.Blog, the Nier pack will be available for those who pre-order by April 9. That gets you a costume to dress up as Kaine or a Replicant from Nier, and your dragon can wear a creepy Emil hat for good measure. Ordering before April 9 gets you both remaining tiers, just like ordering before yesterday would have netted you all three. But of course, Square is holding back on revealing the final bonus.
The game is slated to release exclusively on PlayStation 3 on May 20. Presumably, the final bonus will be available to anyone who pre-orders before the launch.
