Viper

About Viper

Viper is an airsoft MilSim series that reached its ninth edition in 2026. Viper 9 (4–6 September 2026) turned the former military airfield at Dobroslavtsi, on the edge of Sofia, into a battlefield; earlier editions were also played near Haskovo.

The game starts on Friday at 20:00, runs through the whole of Saturday and ends around noon on Sunday, so players bring food for about 40 hours. Three factions take part – Hard Touch Solutions (HTS), Balkan United Forces (BUF) and civilians – with bases in buildings or shelters, generators for the HQs, chemical toilets and drinking water. Open flames are forbidden anywhere on the site.

Highlights

• Former military airfield 15 minutes from Sofia
• Three factions: HTS, BUF and civilians
• Registration and chrono the day before the game

Getting there

Dobroslavtsi, Sofia is about 10 km from Sofia as the crow flies. An easy drive for Bulgarian teams – car-share with your squad, as parking near the game area is usually limited. Always check the organiser’s rules on replica transport, FPS/joule limits and tickets on the official channels before you book.
