Tip for Kill 6 with 1 grenade:
Throw a grenade (fully uprgraded) to take half of their life, make sure there is at least 6 enemies and dont shoot, wait until the grenade is useable again and throw a second one, the second one should finish off the enemies you through the first grenade at.
Probably the best defense game I have ever played!
The whole attitude, dishing out peace with bullets. The rolling around like a badass dodging bullets and ducking like time crisis, puts this miles above all other defense games where you have to stay put and take the damage and have to deal with cumbersome reloads. Fantastically fun game! 6/5
Actually to continue from my last comment, the home screen visual of your character is always running in the background, like the movement of his breathing is constantly going. This is a possible source of lag as it is needless
Just noticed there during a battle, the visual of your character up close on the home screen is still there but behind the battle screen. I noticed this as I had a very long sword equipped and I could see the tip of it moving up and down at the edge of the battle screen
