Alien Invaders 2 is based on the arcade classic space invaders the objective is quite simple really. All you need to do is shoot the alien ships out of the sky while avoiding their shots and collecting free power-ups. Try to avoid getting hit at all for the maximum number of points possible so you can top the leader boards for Alien Invaders 2.
To succeed at this game I found that if you're playing on desktop rapid clicking the left click as opposed to holding it down yields more shots per second and allows you to move faster.
In our play testing I found the game to be a bit jittery to the point where it was more convenient at times to simply go ahead and rapid click as opposed to holding it down due to the "delay". However while testing it on my mobile device it responded significantly better to the point where I would say Alien Invaders 2 plays better as a mobile game as opposed to a desktop one. Make sure to rate the game accordingly and comment below how far you can get on both desktop and mobile!
