11 Bit Studios recently launched some charity DLC in collaboration with War Child that players could buy (for $0.99, $9.99 or $19.99 depending on your willingness to support the cause). Working in places in Iraq and Jordan War Child offers support for Syrian refugee children. This support includes "psycho-social support to recover from trauma, child friendly spaces to make sure War Child can reach a child before someone else does, informal education: school fees, livelihood support, teacher training and others".
Below is an info-graphic with some details of the efforts so far - keep in mind that all of 11 Bit's proceeds go towards the charity. 11 Bit Studios also announced they will offer further charity actions in the future.
