This is Happy Wars Management Team.
The update data released on May 29th for Xbox One and Windows 10 has not yet been released on Xbox 360. Due to the difference in versions, the cross-save function between Happy Wars for Xbox 360 and Happy Wars for Windows 10/Xbox One is temporarily available only one way.
Players can access their Xbox One and Windows 10 accounts even if they have recently played Happy Wars on Xbox 360 with the same account. However, Players who have played on Xbox One or Windows 10 versions of Happy Wars will be unable to access the same account on Xbox 360.
The latest update for the Xbox 360 version of Happy Wars will be released very soon. Once released, players will be able to access the cross-save function normally.
We apologize for any inconvenience caused.
We hope to see you on the battlefield in Happy Wars again soon.

If you want amazing rewards and a lot of Co-op Points, make sure you grab this powerful buff!
Once the season ends, it’ll change into a popular buff!
Once the season ends, Monster Slayer will turn into a different but popular buff.
Even without a special boss to use it on, Monster Slayer will still give you a huge edge in battle! It doesn’t get much better than this!
This time, Monster Slayer will change into one of these 3 buffs:
・Max HP Up Lv3
・Defense Up Lv3
・Shorten Cooldown Lv3
Use Monster Slayer to Beat Bosses and Get Cool Stuff!
Whenever you join a Boss Mission, you’ll get a reward based on how much damage you deal to the boss.

Castle Defense is back!
This weekend’s Special Game is Castle Defense!
Castle Defense is a game mode in which you and your allies protect the castle from wave after wave of monsters!
Prepare for long battles full of suspense and test your mettle against increasingly stronger enemies!
After each wave, you will receive meat, an item exclusive to this game mode.
By eating meat, you can improve parameters such as attack damage and the strength of tactical weapons.
Teams that manage to battle through enemy waves fast enough will find themselves facing a revived Big Boss Jinn… and he’ll be even stronger than before!
If you’re looking for a challenge, hard mode won’t disappoint! But keep in mind: only the truly prepared should dare to challenge hard mode, as even the strongest veterans may find themselves overwhelmed!
Last but not least, players who manage to inflict a lot of damage on the Big Boss will have a chance to receive the mystical Desert King Cleric Set! The more damage you deal to Big Boss, the more likely you are to earn pieces of the set!
