Castlevania: Belmont's Curse English Voice Cast Revealed, With Liam O'Brien Back as Isaac After More Than 20 Years

Konami has revealed the English voice cast for Castlevania: Belmont's Curse, dropping a dedicated trailer during the lead-up to Gamescom 2026 and locking in the studio's confirmed October 15 launch window for PlayStation 5, Xbox Series X|S, and PC, with a Nintendo Switch version planned for a later release.

The trailer spotlights Liam O'Brien reprising his role as Isaac — the sympathetic forged-knight ally from the Netflix Castlevania animated series and Symphony of the Night legacy — marking O'Brien's first appearance in the franchise in more than twenty years. Around him, the showcase introduces the wider English ensemble for the studio's new Belmont-led entry, alongside fresh story beats and a quick look at the gothic action combat that has defined the series.

The October 15 date was first surfaced earlier this year alongside Katsuya Terada-illustrated character art that introduced a new female lead, anchoring the game as the studio's first mainline single-player Belmont title in over a decade. With the cast reveal, the studio has finally put a face to the player-character roster English-speaking players will hear at launch.

Our Take

Konami is playing the long game here. Pairing a returning voice actor like O'Brien, who has decades of credibility with both Castlevania and D&D-adjacent audiences, with a brand-new lead and a Switch follow-up signals a willingness to launch the game to its strongest console base first and treat the Switch port as a deliberate second wave rather than a rushed day-one release. With Gamescom opening later this week, expect hands-on impressions and a deeper story breakdown before the October 15 launch.
