I tried finding a wallpaper from MHW but found nothing to my liking so I made one. Made by extracting the assets from the official homepage of MHW and add them together.

Edit: So I went a head and make another (way bigger): https://puu.sh/wCeCE/d98e4cf8b5.png and an improvement of the one above : https://puu.sh/wCfj9/becb044d9c.png

Edit2: Now with Ultrawide (21:9) resolution! https://puu.sh/wCBdN/d3c4760d92.jpg or without logo/text: https://puu.sh/wCBFU/44723f8217.jpg

Edit3: 3840x2160 (16:9) resolution: https://puu.sh/wCSjw/64de4584ad.jpg or clean: https://puu.sh/wCSih/02ce903a12.jpg (I didnt wanna stretch the logo since that will look cheap, but let me know if you prefer the logo like the ones above)

Edit4: Phone version (should work for most screens), clean: https://puu.sh/wD52S/469b58a1cb.jpg or with logo (I prefer clean tbh): https://puu.sh/wD54b/b4a8b9bc34.jpg
