UK-based Mac game developer Virtual Programming has updated one of its popular strategy games and introduced a bundled product offer for many more.

The company has released a download only $9.95 update, Armageddon, a follow-up to Hearts of Iron 2: Doomsday. The action begins where Hearts of Iron II: Doomsday ends.

Armageddon will include two completely new alternative history scenarios with variable end dates. The software – which requires Hearts of Iron 2: Doomsday – be installed, also offers new gameplay elements, including upgraded Naval and air combat systems.

The company has also announced its 'Strategy 6' compilation of six strategy games from Paradox.

This collection includes Europa Universalis II, Crusader Kings, Victoria, Victoria Revolutions, Hearts of Iron 2 and Doomsday. You can buy all six games for $39.95.
