Nova Defender

A lone turret, a horde of angry ships, and just enough scrap to turn the tide—welcome to Nova Defender.

Nova Defender drops you behind a single cannon on a dark little platform with nothing but empty build plots and a bad feeling. Enemies don't trickle in; they roll in from multiple sides the second the first wave starts. The loop is tight: blast them, catch the scrap, slam down a new turret before the next wave hits. That loop is what kept me glued for an hour. There's a proper sense of panic when a shielded cruiser shows up and your lasers just tickle it. You'll find yourself selling a wall to afford an upgrade, or praying the spread shot turret aims the right way when a swarm comes over the top. The build grid is small, so every structure is a commitment—no wasted corners. I lost my first run because I built too many generators and not enough guns. Lesson learned. It isn't a slow-moving tower defense with prep time. Nova Defender is meaner and faster, closer to an arcade score chase where your base layout is a weapon. Some runs click and you're untouchable; other runs a single shrapnel rat gets through and it's over. That tension is the point.

You can build other buildings using the resources that drop from defeated enemies.

Get a second turret down before upgrading anything; early damage trumps one big shot. Corner walls beat front walls—they stall enemies at an angle your turrets already like. Sell the first generator if a wave is about to spawn and you're short on scrap. Watch which flank the fast shrapnel enemies take and set one spread turret to cover it fully. Upgrade range before damage on long straight lanes; it pays off against distant bombers. Don't hoard scrap during boss waves—drop every turret you can afford.
