Videogame, simplified chinese localization

Hello, everyone! We are a dev team and we need to translate our videogame from english to simplified chinese. The game is an FPS with a sci-fi/robotic theme. The content to be localized is relatively small, around 5000 words, mostly some lore about the machines you fight in game and the Steam store page description. The rest is menu labels (settings, graphics, audio, new game, exit and the like).
We are working with Unreal, so we will provide you with a .po file, that you can easily edit online or with free softwares like https://poedit.net/
The Steam store page description will be provided as a txt.
Cheers!
