Here’s app release note :
“In Crimson: Steam Pirates, plumes of black smoke fill the blue Caribbean sky as Thomas Blood’s pirate fleet steams ahead—over, above, and below the waves. On the surface, ships bristle with swivel cannons and lightning guns. Above, zeppelins drip with incendiary bombs. And below, silent and deadly, submarines stalk their targets, torpedoes at the ready.
Command your fleet and your Steampunk crew using an elegant action interface. Crimson: Steam Pirates’ turn-based gameplay provides an addicting mixture of strategy and action as you anticipate your enemies’ moves and counter them, luring them into a deadly hail of weapons fire while uncovering the mystery brewing in the Caribbean.â€
