Gameplay
Underground War 2.0 gameplay — tunnels, flag, and nuke
Game overview
Red vs Blue tunnels, swords, snipers, and one shared nuke
Underground War 2.0 is capserg's 2022 Roblox remake of Stickmasterluke's 2008 classic. You pick Red or Blue, spawn on your fortress half, and spend a short round digging dirt, fighting with a shovel, sword, and sniper, and chasing the enemy flag. Kills and captures feed a shared point bar; when that bar is high enough, someone can launch the nuke from mid-map and wipe the other team after a 15-second countdown. Cash and rank XP stick between rounds so upgrades matter. Start with the getting started guide, claim the current promo codes, then check the weapon tier list before you dump Cash into the wrong tool.
