Call to Arms is a real-time tactics and strategy video game developed by German company Digitalmindsoft as the spiritual successor to the Men of War series.

[7] Kramer also said that Digitalmindsoft was designing a new cooperative system relative to Assault Squad.

[14] Digitalmindsoft wanted to include "integrated in-game video capture software", and support for Steam was assumed.

[15] While Digitalmindsoft was funded to begin the project, the company sought crowdfunding as an extra source of revenue, offering better game performance and content as well as a list of rewards for stretch goals such as "skill-based matchmaking and support for Steam Workshop and Steam Cloud".

[17] ShackNews and PC Gamer expressed reservations regarding crowdfunding, qualifying them due to the company's experience in this genre of video gaming and the fan base for the Men of War series.

[12] In March, Wargamer reported that project had been crowdfunded for €5.5 thousand with less than a week left in the campaign, though they were informed by Digitalmindsoft that this was not the final goal.

[18] That July, Digitalmindsoft announced Men of War: Assault Squad 2 with a release date of Q4 2013, leaving both RPS and ShackNews confused about the status of Call to Arms.

[20] PC Gamer was skeptical about the crowdfunding, as Digitalmindsoft had raised only 25% of the funds the developer expected,[14] while PC Gamer was optimistic regarding the schedule and thought that the publication of Assault Squad 2 would give financial profit for the company.

[3][15] Digitalmindsoft revealed a standard and deluxe edition, "Domination" game mode, play with bots, and a map and mission editor.

[15][24] Polygon and PC Gamer named Call to Arms to their top-100 lists of games to-be-released in 2015.
