Heavy Barrel
P1 W1 // 0 / 6
Spin the gun with the mouse wheel or Z / C. Weapon and EMP drops can fall from defeated enemies.
Controls: Move with WASD or Arrow Keys. Spin the gun with the mouse wheel or Z / C. Fire with Left Click or Space. Dash with Shift. Use E for EMP. When all parts are collected, press Q to unleash the Heavy Barrel.
Mission: The battlefield pushes from the bottom of the screen toward the top. Break the depots, survive counterattacks, collect the six barrel parts, stack gun upgrades from fallen enemies, and reach the extraction zone. Press P to pause and R after a mission ends to restart fast.
Heavy Barrel Tribute
Built as an original homage to that old-school top-down run-and-gun energy. The stage now rolls from the bottom toward the top, your gun spins with the mouse wheel or Z / C, and bunkers carry the six barrel parts you need for the superweapon.
Briefing ReelOperation Start
Push north through the jungle road and break the battery line.
How It Plays
Push the road. The operation drives north through jungle roads and fortified chokepoints while enemy bunkers keep reinforcing nearby troops.
Collect the parts. Each bunker drops two golden barrel parts, giving you a reliable path to assembling the weapon.
Use the window. The superweapon is temporary, so it works best during the extraction rush when the whole map starts collapsing on you.
Controls
1P: Move with WASD or Arrow Keys, spin the gun with the mouse wheel or Z / C, fire with Left Click or Space, dash with Left Shift, EMP with E, Heavy Barrel with Q.
2P: Move with IJKL, rotate with U and O, fire with Right Shift, dash with Right Ctrl, EMP with Slash, Heavy Barrel with Backspace.
Tuning: Enemies go down in one hit, gun pickups widen your volley step by step, and EMP stock starts loaded with extra refills dropping at random.
