Putin Must Die

Vladimir has gone mad. He has created an army of Russian-speaking Putin clones to destroy America, and the White House is the final frontier.
You must defend the White House against invading hordes of Vladimir clones, or die trying!

Your arsenal of weapons include:
A jetpack (made in China)
A trusty Handgun
Shotgun (delivers deeply satisfying headshots)
Sniper Rifle (for trickshots)
Presidential Grenade Launcher
Automatic AR for blasting Putin to pieces

Zombies have Procedural Dismemberment. So you can blow them to literal pieces!

You must keep the White House from destruction as long as possible, whatever it takes.
