OP90 is a cool little arcade games with a bit a nod to retro games like Galaga.
You need to stop the assault heading towards you using different weapons dn tactics. It is not just fastest on the trigger in OP90, you need to think a little to and puzzle some things out.
Use W and S or Arrow Keys to move up and down, A to shoot beam, D shoot the cannon, A&D shoot signal to trigger the drones.
The game is also coming out on iOs and Android, where it will work with tilt and touch. It uses Unity.
OP90 is something a little different, well worth a go.Autosaur updated this game on 11 Aug , 2015.
