Hold the line. Grow your army. Break the swarm.

Swarmfront is an arcade lane shooter. Your squad fires on its own; you decide where it stands. On the left, endless swarms march toward your sandbags. On the right, powerup crates drop in and need to be shot open. Every second you spend on one lane, the other gets closer. Choose wisely.

Features

• Build an army. Grab recruits from crates and blue gates, and dodge the red ones. Gather enough of one rank and they merge into stronger troops, from Recruits all the way up to Titans.
• Specialists. Unlock heavy hitters with a Cannon, Machine Gun, Rocket Launcher or a sweeping Flamethrower.
• Four worlds, four megabosses. Neon, Desert, Ice and Lava. Each world has 8 waves, its own enemies and twists (shielded foes, fast insect swarms, erupting lava), and a megaboss at the end.
• Heroes. Lead with the Commander, who boosts power and calls a charge every 18 seconds. Or unlock the Medic, who heals specialists and brings fallen recruits back.
• Progression. Earn XP every run, level up and spend points in three skill trees: Attack, Command and Survival.
• Plays anywhere. Keyboard on desktop, touch buttons on mobile, with a quick interactive tutorial and a graphics quality setting for older devices.
