[New Fire Emblem Heroes Event (More Maps) Need help Translating the Japanese]

So a new tweet from the official account sounds like it says there will be a new map related event starting, which will hand out Orbs but I need help translating it to better understand it.

【予告】 明日2/6(月)16:00より、スペシャルマップに「リリース記念プレゼントマップ」が登場！ひとつのマップでそれぞれ３個、２つの難易度で合計6個のオーブが入手できます。これから５週間毎週１つずつマップが追加されていくそうなので、なんと合計30個！ #FEヒーローズ

Can anyone help?

 

I want a translation, not a google translation as that keeps coming back with conflicting comments.
