For clubs day today, more than 100 groups will fill the museum reserve, or the link building in the case of rain.
Otago University Laser Tag Society secretary Joel Bartlett said the club he created, which is now in its third year, was a great source of exercise and created a community of friends.
''It's just fun. You meet a lot of cool people.''
He estimated it had more than 50 members.
The game consists of running around a dark indoor maze, shooting lasers at illuminated packs and guns other players are holding.
The club held events twice a week at Megazone Dunedin, including one ''league training'' on Tuesdays and a members' night on Sundays which could attract anywhere from 15 to 30 people, he said.
While a game lasted 10 to 15 minutes, some sessions went on for hours.
''If you train, you get pretty good. When I came back after being away for a while, after game one I was exhausted.''
The teams took the game seriously, creating code words and formations to outsmart opponents.
''Everyone's just yelling at each other. Random words that mean something to us and hopefully no-one else.''
The club is partly responsible for putting Dunedin on the laser tag map, as it now competes with the nation's main player, Auckland.
In recent years, Megazone has improved its laser tag facility, and now holds nationwide ''invitational'' tournaments.
Dunedin was becoming competitive with Auckland teams, Mr Bartlett said.
''For example, there were 30 people in the invitationals, and out of the 10 Dunedin players, eight got into the top 20, and two into the top 10.''
His advice to new players was to stick to corners and keep guns away from their bodies.
