Create a 3D game (or application) in 79 hours - it’s real!
Join the UNIGINE online hackathon: show your creativity, find new friends, level up skills, add a new project to your portfolio, get cool prizes! 3 days of the concentrated drive, from January 28 to January 31, 2021.
If you do not have a complete team yet - it does not matter, after registration, you will be able to join other programmers and 3D-artists.
How to register?
1. Join our Discord server (discord.com/invite/gFN7w9b)
2. Then write a private message to our bot @UNIGINE with your email
3. Create a team following the bot’s instructions
All the details are on the hackathon website https://l.unigine.com/2s2bY8pvy
P.S.: A hackathon/game jam is a marathon for developing applications or games, where a team of programmers and artists creates a project from scratch in a limited amount of time.
P.P.S.: Get UNIGINE 2.13 Community SDK: https://l.unigine.com/IOcD5yGuB
