Gigantic - free trial

I just got an email, that the previously closed MOBA shooter Gigantic is having a free trial period after it's been relaunched. I also got 4 free keys to share. The keys can be used in the Arc Client, so they are not for Steam; if it bothers you, don't bother to comment on it, this is not my choice.
Have fun! The trial ends in a week.
