[h1] Similar to tower defense game, fly your mothership to infinity and beyond. Build new guns and place them in designated spots, improve shields and general speed. Each level takes a bit too long though. Generally it's not bad, but badly balanced. Couldn't finish last stage because thrusters were improved to the max so I got overrun by enemies. If you want to play this one make sure not to upgrade speed too much or last level is gonna be impossible to complete. [/h1]

This is not a fun game. It should be used as punishment for convicted felons to save space in prisons. some basic ideas borrowed from every tower defense game you've ever played, slopped together into a shake'n'bake cash grab of repetitive, stale gameplay, with broken english scattered throughout the interfaces. Add to that some absolutely insane difficulty spikes, which punish you for upgrades that you only later realise you shouldn't have paid for, but cannot be undone. Avoid.

Recommended Aug 6, 2026

Good but I got so powerful the game was so laggy I had to stop playing it. I don't even think having a good PC would help but its okay would be something you would have played in 2005 on some flash website it seems. 6/10
