Hi, This is Janus Labs. We would like to give you the encouragement to be healthy and safe from COVID-19 prior to notice about the update. There is 4.0 update today. The game can still be played by limited users like the backers. The official release through the publisher is scheduled for sometime this year. [Update Note] 1. DUO Mode : Now two players can stand on the same side and fight together. Try together to defeat your competitors and survive to the end. 2. Defense Mode (co-op Mode) : This mode protects the basecamp from incoming enemies with up to 4 players. Beware of the mighty boss troops appearing in every 10th wave! 3. Intro Video : It has been added to introduce the game background. 4. Character Skin for the backers : You've been waiting a long time. Limited character skins for the crowdfunding backers have been unveiled. Please input your gift key to get the rewards.
