August #ue4jam Update

We had an excellent turn out for this month's jam with 48 games submitted for the event, themed "Things Are Not Always as They Appear." The results were scheduled to be revealed on Twitch this Thursday, however, we unfortunately have to push the announcement of the winners to next Thursday, September 1, due to the inability to download the games from the submission thread. We are truly sorry for those of you awaiting the results, and we are looking into ways we can avoid this situation in the future.

No Livestream This Week

For the first time ever, we're having to cancel our regularly scheduled Thursday livestream at Twitch.tv/UnrealEngine due to the circumstances outlined above. We will pick up again next week with our live training series on Tuesday and have a special surprise in store for Thursday, Sept. 1 alongside the August #ue4jam results. I cannot wait to reveal more on the topic soon!

We want to thank you all for your patience while we continue our investigation surrounding the forum compromise, and we apologize for any inconvenience the outage is causing you. Keep an eye here on the blog and our official Twitter account for updates.
