Altitude demo expanded and unlimited

[lamster]

The Altitude demo available from http://altitudegame.com/ and Steam has no time limit and includes access to all 5 planes (1st red perk, rubber hull, heavy armor, turbocharger). This perk set includes choices that are viable both for casual and for competitive play. If you enjoy Altitude but can't afford to buy it, please stick around, our community would love to have you.

Players can unlock access to the remaining perks at any time for a one-time purchase of $10.
