About
- Ireland's collegiate esports league returns for its tenth season. Open Division Winter Semester starts 12 October.
- Season Ten of the Ireland Esports Collegiate Series is open for registration. Red Bull Ireland are back as Official Partner. And the Open Division is getting a LAN of its own — not just for the finalists this time.
- We're committing to an Open Division Invitational LAN in the spring — on campus, in student gaming spaces rather than a venue rented for the weekend, and open to far more of you than a finals night ever could be.
- Invitational, and deliberately not a winners' bracket. This isn't a reward for whoever topped their title. Places will be prioritised for players who compete across both semesters — so playing Winter and Spring is what puts you in the frame, not where you finish. Full criteria and venues are being confirmed now, and we'll announce them during the season.
- And Open Division finals weeks now carry the live broadcast. December and April, cameras on you.
- Rounds start on 12 October and finals week is now locked in for w/c 30 November, before exams kick in.
