Long Answer: I just started playing Warhammer Quest this morning and I'm having a great time. I've never played the original, but I have played my share of Dungeons and Dragons: Castle Ravenloft Board Game and it plays similarly. It even runs well on my iPhone 4, which is more than I can say for Star Trek Rivals (which I also enjoy, but this simple card game runs like chunky peanut butter).
Anyhow, if you're like me, you may have run into the situation of not being able to exit or leave the Equip Screen. Also, if you're like me, you probably have no idea how you got there to begin with.
Apparently you rotate your iPhone vertically to access the Equip Screen. Clever, but it's never taught anywhere. Sometimes the game will put you in that mode randomly and if you have your screen rotation locked, you can't get out of it. What the heck.
Anyway, turn off screen rotation lock if you want to play Warhammer Quest.
