The launch of Overwatch, a first-person shooter game developed by Blizzard Entertainment, drew a snaking queue of fans outside Capitol Theatre on Saturday (May 28).
The queue started on Friday night and by 3pm Saturday had swelled to over 1,000 fans, who spilled out of the theatre foyer and circled around the building.
They were all lining up to enter Capitol Theatre, which has a standing capacity of less than 500 people.
Doors to the theatre opened at 3pm, and inside there were consoles and PCs available for fans to try out the game, and also booths for them to take pictures or get their caricatures drawn.
Fans could also buy copies of the game as well as merchandise, and watch show matches between professional teams.
The event was attended by Blizzard software developer Bruce Wilkie, who flew in from the USA just for the launch.
Speaking to The Straits Times, he said: "It's very humbling to see all the fans.
"As much as the game inspires fans, fans inspire developers, and it's great to see."
The event takes place from 3pm to 9pm, Saturday and Sunday (May 28 and 29).
