Warhammer 40khas always had various cards and extras to pay attention to during a game. I remember hidden objectives from back in the 2nd edition days. Plus, there were the various tactical cards to deal with as well. Even though I've not really kept up with 40k, apparently they've kept up with having such cards and objectives for missions. Derp Studios is now here to help out with that with their Warhammer 40,000: Tactical Objectives App, available soon.
The app contains all 36 Tactical Objective Cards, as well as information on all of the six Maelstrom of War missions. That way, you have all that info on your phone or tablet and don't have to worry about the cards, themselves. As a bonus, the new Cities of Death Tactical Objectives and Missions are available at the initial release as part of the main app purchase.
The app is designed for Apple, Android, and Windows 8 devices.
