Warning : Just like the original game did, this game's visual effect may cause photosensitive epilepsy for some people. Be careful if you had a hard time playing the original defender or stargate.

This is a port of Eugene Jarvis' legendary title Stargate, a sequel to Defender.
I did my best to make it as faithful as possible but the difficulty is intentionally lower than the original, so it won't be so frustrating.
Protect 10 humanoids from the aliens and prevent the planet destruction. Your new friend, Stargate will help your mission by quickly sending you to the desired area when a humanoid is in danger. By collecting 4 humanoids and getting into stargate, you can warp 3 waves.
Controls :
X : fire laser
Z : Invisto
Z while holding X : Smartbomb
Z when you had ran out of invisto : Hyperspace
