I'm a Warframe player, and this is a topic on the Warframe forums atm, The central icon (Seductive) in the below image, is clearly and directly ripped from another game, Warframe... In fact, it's Warframes primary icon used literally everywhere in the game as a reference to The Lotus, the main narrative character voiced by Digital Extremes Community Head.
Any comments from the Devs?
I know art assets are easy to just lift off the internet but jeeze at least try and get some free images you can use, I expect Digital Extremes will contact you if they have not already.
