Scrapswarm 3D is a free survivors-style browser game with a base-defense twist. You are RIVET, a welder-bot stranded in a dead city. Your rivet-gun fires on its own at the nearest enemy, so you focus on moving and dodging the endless scrap swarm — then, between waves, you weld your own defenses from the scrap you harvest.
Move with WASD or the arrow keys on desktop, or drag anywhere on a touchscreen. RIVET auto-fires at the nearest bot and turns to face it. Kill enemies to collect scrap and level up, drafting a salvage upgrade each level. When a wave is cleared, spend scrap to weld turrets (auto-fire), barricades (block paths), or a repair, then hit Start Wave for the next, larger swarm.
Between every wave you enter a build phase. Because RIVET is a welder, you spend salvaged scrap to weld auto-firing turrets and barricades that fortify the arena — combining an auto-shooter survivors loop with light base-defense.
