Could you write the full model name of your Chromebook?

Well. I know a tested way how to run it on similar model.
1) download version of Warnament for linux
2) open folder of this file in terminal
3) try to run using ./Warnament.x86_64
4) if there are some errors, try:
a) chmod +x ./Warnament.x86_64
b) sudo apt-get install libopenal-dev
c) sudo apt-get install libglu1
If it doesn't help, please write me in Discord
