Your support is needed WWIIOL Community!

We've officially launched the 2019 Funding Campaign for WWII Online, which is designed to provide the game with an entirely new server facility, built from the ground up with all new efficiency in terms of performance and power. It also means we'll be transferring WWIIOL from Dallas TX --> Portland OR, where CRS HQ is located. 

We'll also be renewing some critical game development software, and upgrade our SpeedTree server development kit to the latest version, allowing us to have enhanced graphics for terrain objects.There's a lot more, please check the funding campaign below for a video presentation and a detailed written explanation of what more is to follow.

Tonight's hot fix being released will focus on fixing two client crashes, an AWS issue and a couple of manuals got repaired. We'll also be adding some anti-griefing stuff and an automation to make mission creation a tad bit easier. Great for players, is the re-addition of the "Player Ping" information which has now been color coded for good - neutral - bad connectivity. We hope this feedback is used productively so you can make modifications on your end, such as getting off that WiFI / going hardline ethernet for best packet transmissions. Also new, you guys can change the color of green tags (new players) for the first time. Please keep reading for specific details.
