Sonic Frontiers has sold 2.5m copies worldwide, just over a month after it released on 8th November.
The news was shared by Sega on its official Japanese website and Twitter account.
In comparison, total sales of the Sonic franchise over the previous financial year were 5.8m, meaning Sonic Frontiers has achieved almost half of that in one month. 2017’s well received Sonic Mania reached 1m sales in one year.
