Learn About the Game Battle Gear Underground 4
Battle Gear Underground 4 throws you into tunnels alive with action and strategy. You explore forty levels carved in rock. Each stage hides traps and shootouts that force you to adapt. You pick one of four routes and send squads down separate lanes. Your team can include infantry squads artillery crews and fighter planes.
Timing decides each clash. You drop bombs from the air and build defense towers along trenches to hold off attackers. You upgrade troops with stronger armor or faster engines. Medals track your wins on every run. You finish a level then walls shift and paths change. You rethink each play to keep foes on the back foot.
You move the camera with A D or arrow keys. You zoom through tunnels with Z X or C. Clicking the mini map takes you straight to hotspots. You press numbers one through nine or click a unit icon to deploy troops in a lane. You tap Q through U or click icons to switch between infantry artillery or planes. You assign a special skill to a unit before you launch it into battle.
