Thank you Kristiyan !

Yes TuckerTrucker, it's broforce. I am a fan of this game. I had the idea to use the graphics engine of the game to create an animated pixel art scene with a cyberpunk atmosphere that isn't present in the original campaign. So I personnally used the level editor, it took me already a lot of time to have my own level. And after that, I still had a lot of work on GIMP to do to build a such wide gif file because the camera gave me a lot of problems (for example it wasn't possible to record all the whole scene (too big) with one point of view). So yes, it's just broforce, but without any agressivity, it's just hard work too :).

Thank you faqinhell :) !

Unhappily, it's very hard to me to fix that : actually the background is composed by a very wide gif animation. This animation was made using the level editor of the game Broforce. I created my own level with that special atmosphere which is not present in the original game. I recorded (with a lot of time and camera problems :)) the animation on my level and made some adjustments on GIMP. To enlarge the animation, i would have to create another piece of the scene which means to change my level and then record an animation of that piece and finally put together the old gif file and the new piece, which is practically, very hard and time consuming. If one day i have the time for that, maybe i ll do something but with all my respect, do not expect something certain ;).

Thank you :) !
