If you're a Bleach fan, this game is for you.
In Story Mode, well... it's a mode that has story... All in all, it has about 7 or 8 episodes. Each episode has it's own theme from the serious episode of the battle with the arrancar, to the very funny episode about the women's Soul Society meeting. However, the whole game is about 95% Japanese which means, if you don't understand Japanese, your'e going to miss out on the hilarious Bleach humour as well as the gripping Bleach dialogue. I don't understand Japanese too much, but I do know a bit from all the episodes of Bleach that I have watched and believe me, eventhough you don't understand Japanese well, you will still be chuckling and giggling as well as laughing out loud from the Bleach humour. Playing story mode will unlock battle arenas to play in Free Mode as well as snapshots from the story that can be purchased from Urahara Shop.
Now for Battlers Mode... In a nutshell, Battlers Mode is kinda like a board game where you start on a single square with 2 characters (Ichigo and Rukia) but as you keep defeating all the opponents there, you will advance to the next square and unlock characters. Get it? Each square on Battlers Mode has a specific colour. The red square means it's a free mission where they will give you an opponent (or sometimes 2!) to battle with but you can select the character you want to use. The blue square means it's a challenge mission where it's the same as free mission but the game will give you the character to fight with and sometimes with certain conditions such as their special meter is full or maximum and your life bar is only half while your opponent has 2 full lives. I played the whole game in normal difficulty, and while there were some very tough challenge missions, none of them seem to be impossible. Challenge mode can also relive classic battles in the anime such as Ichigo going against Byakuya. Even the location is correct!!! (Soukyoku Hill). After completing each mission, there will be a screen where there are 3 objectives to be completed in each mission. Each objective you complete, will be awarded with a crown. After obtaining 50 or 100 or 150 crowns, (and other milestones) more squares will be revealed with more challenge missions. And the review by Skip04 is right, if you don't know Japanese, you will have trouble completing Battlers Mode.
There are also a lot of extras to unlock in this game. There are little items to be bought in Urahara Shop which you can put on the characters such as hats, boxing gloves, and a lot of other wacky stuff. (there's even an afro!!! Just imagine putting an afro on Ikkaku... Hilarious!!) You can also buy the snapshots that I mentioned earlier. There's even 3 videos of Kon's radio show which you do not need to buy, but is unlcked from Battlers Mode (I think) as well as characters and arenas which are nlocked from Battlers Mode and Story Mode respectively and are also unlocked directly and do not need to be bought. There's also a Tutorial and Training Mode which I thought was unnecessary because of the simple gameplay.
All in all, Bleach: Blade Battlers 2nd is a very fun game especially for Bleach fans such as myself. Non Bleach fans however, aren't going to enjoy it as much as Bleach fans, but they will still enjoy the simple gameplay and controls which can picked up by just about anyone. Along with the billions of unlockables that will be keeping you playing for a long time, as well as the solid fighting mechanics, this game is a must-have for Bleach fans as well as fighting game enthusiasts.
