It is more an RTS than a 'classical' wargame, but you could do it in Warzone 2100. It is old for now (but it was very fun in 2000s). It could be fun for you today. There is a free and open source version : https://wz2100.net/ . Source: 6 months ago

It's free at wz2100.net and it's tiny, mere megabytes. Source: 11 months ago

The way he got it was by killing someone with his current melee, and somehow after the kill, it switched to "maul", kind of like how in surviv.io after you got a kill with something in potato mode. Was this a bug, or intentional? I also believe that the "maul" will most likely be used to break the black square stones that you can't break with anything else, like the hammers did in surviv.

This subreddit is shut down. You used to be able to play a resurrected version of surviv.io at https://resurviv.io. Now, it redirects to the discord server for a new game, Suroi, which has its own subreddit, and is kinda like the original game. Source: 11 months ago

I wish I could play surviv.io again, the season expired so long I didn't play cause my Google can't handle it a good thing I got my Avast but when I check it doesn't really work I go to more websites and it just doesn't work. Source: about 1 year ago
