Hi
Remember the Space shooter lecture?
I shared my version with u, and it was nice.
After I finished the course, I began to do Invasion Survival 2 game, with all my knowledge
I put my soul into this, and I am proud of it; It is for android only
I have a paid version without ads too, buy it if you want to support me 
I CHALLENGE ALL OF YOU TO REACH WAVE 40 AND BEAT THE FINALL BOSS 
Do it and you will have my respect. It won’t be easy hehe 
I use ads from Unity ads because I found them very easy to implement;
I done my first dollar in 2 days just from the ad version. I will do another game after I finish the 3d course. If I get some decent donwloads on the paid version, ill buy all courses from you
Here is the GAME
