As promised – and while the Arma 3 Alpha leads Steam’s Top Sellers chart since launch – Bohemia Interactive today made a free invite-only variant available. The Arma 3 Alpha Lite is a limited version of the Arma 3 Alpha, providing people with the opportunity to try out the singleplayer showcase missions, a selection of weapons and vehicles, and the scenario editor.
Unlike the regular Arma 3 Alpha, the Arma 3 Alpha Lite does not feature a multiplayer component or modding support, and does not include access to the Arma 3 Beta and complete game later on.
To participate in the Alpha Lite, people need to be invited by those who have purchased the regular Arma 3 Alpha. The Arma 3 Alpha Lite will be discontinued on June 18th, 2013.
Upgrading to the complete Arma 3 Alpha can be done by purchasing the Arma 3 Alpha (24.99 EUR/19.99 GBP/32.99 USD) or Arma 3 Digital Deluxe Edition (39.99 EUR/34.99 GBP/49.99 USD) on Steam. Extras in the Digital Deluxe Edition include a digital soundtrack, digital maps, digital tactical guide, and a Steam Gift of Arma: Cold War Assault (formerly known as Operation Flashpoint: Cold War Crisis).
Both versions provide access to the Arma 3 Beta plus a digital version of the complete game upon release. The price of each edition will increase once the Arma 3 Beta and final game become available.
