The first playable alpha of VietDoom has been publicly released.
This alpha contains 5 levels (Map01, Map02, Map03, Map04, and Map09).
Keep in mind this an ALPHA, it has some bugs... many bugs to be honest. But you can play the demo levels just fine.
Check the files section to download it.
I have also opened the forum for reporting bugs (oh I know there will be a lot of them).
Here are some videos showcasing the four first levels.
We also have an official server for playing online on Zandronum:
