INTERESTED IN WORKING FOR US? MAKE SURE TO PARTICIPATE!

This mission jam is going to be special, because OPR is currently looking to hire freelance designers to create official missions for our various narrative campaigns, mission packs, and more.

We're looking for someone with native-level English writing skills and a good understanding of OPR games to design ~10 missions a month for all OPR games (including Quest games, currently excluding Warfleets). The ideal candidate loves our games, can work independently, is meticulous in writing missions following the exact OPR format, and needs to have MS Word. Note that typically it takes 30-60 minutes to write a mission depending on the skill level, so this is the perfect job to spend a few hours on during the weekend, for example. This is a paid position, and our hope is to find someone that can easily fit into this role, and maybe one day expand into additional game design work at OPR.

If you meet the requirements above, and would like us to consider your submission as a job application, then make sure to add [JOB APPLICATION] to the title of your submission, so we know who to contact. 

Thank you and good luck! :D

Note: The mission writers retain the rights to their own missions, and they won't become part of OPR's catalogue of missions unless specifically agreed between the creators and OPR after the jam.
