Lane Clash

In the developer's words

Shoot the gates. Grow your squad. Hold the line. Your squad fires on its own; you just pick the lane. On the left, shoot red gates until they turn blue and walk through them to gain soldiers, and break crates for fire-rate and damage boosts. On the right, monsters march toward your line, and every one that gets through costs you troops. How long can you hold out? - No ads, no in-app purchases, noFrom the game's page on itch.io
