PlayStation All-Stars Battle Royale isn’t a smash hit, and now the studio that handled development of the game is laying off employees.

Superbot Entertainment let go a portion of its workforce today. Sony provided GamesBeat with the following statement:

SCEA can confirm that SuperBot Entertainment did make a reduction in their workforce today. The studio and SCEA remain committed to supporting PlayStation All-Stars Battle Royale post launch, including developing the title’s forthcoming DLC releases in the coming months. The first character pack (including Kat from Gravity Rush and Emmett Graves from Starhawk) will be available for download on February 12 and will be free for the first two weeks. We’ll be sharing news of additional upcoming content soon.

According to social-networking site LinkedIn, an animator, a U.I. designer, and a gameplay programmer all updated their profiles to indicate they ended their employment with SuperBot this month.

PlayStation All-Stars Battle Royale debuted on the PlayStation 3 and PlayStation Vita in November. Critics were positive-to-mixed on the fighting game, which took many of its design cues from Nintendo’s Super Smash Bros. series.

Sales of the game weren’t stellar. It failed to chart on The NPD Groups 10 best-sellers of November or December.

As Sony mentioned in its statement, the first new character pack for the fighter will hit PlayStation Network on Feb. 12.
