In case anyone's interested in Osprey Publishing's historical military combat books and wants to pick up a few cheaply, Humble Bundle has been repeating one of their previous offerings as the
Humble Total War Bundle Encore as a weekly bundle expiring tomorrow on Thursday at 11 AM Pacific Time.
For the minimum $1 at the lowest tier, you can get all 3 ebooks, as well as Steam keys for the games, and of course if you want more games you can go up to the $15 top tier and if you want a T-shirt as well, you can go to $30.
It's got 2 of Osprey's books on particular ancient Roman battles (details in the
write-up for the original bundle in the post here), plus 1 novelization of one of the game campaigns.
