If you are into shoot and survive type gaming. Then dead trigger is one game that you should check out. It's one game that's been making the rounds on android. And they seem to be getting a lot of downloads. You can check out the gameplay where you can see how the game works.
Yes I'm very much into that type of game. It reminds me of another game I played where I was shooting zombies. I might play this one too if I find it on the playstore.
