I've decided to add kill streak rewards to the game! The setup will be very similar to Call of Duty Modern Warfare 2 kill streaks. There will be ten kill streaks in total and you can only choose three. Each kill streak requires you to kill a certain amount of zombies without dying and if you get to the specified amount (while that kill streak is choosen), it'll pop up. Now ten is the number so far, but I may expand it if you guys have any ideas for new ones! I'm going along the lines of "military weapons/vehicle support & religious holy weapons support". Here's a list of what I have thought up so far...
Ammo Drop [20 kills]
When you use this, you'll gain extra ammunition for all of the weapons that you have unlocked so far. The amount of ammo you gain is equivalent to buying two of each ammo from the equipment store.
Light Bullets [35 kills]
After activating this, all of your bullets will be full of light and their damage to enemies will double. This will last for 45 seconds.
Undecided [... kills]
Undecided [... kills]
Circle of Protection [65 kills]
Place a holy cross on the ground and a circle of light will emerge from it. You can move in and out of the circle at will, but the zombies will not be able to walk into the circle. This circular shield will last for 1 minute. You can also move the cross once you place it, but the barrier will disappear while you're moving it.
Instant Kill [75 kills]
Any form of damage will kill a zombie instantly. Very handy when you're facing demon zombies in the later waves. This powerful reward only lasts for 15 seconds.
Influence Gas Grenade [100 kills]
When you reach this streak, you'll be able to use one special grenade. When you throw it, the grenade will shoot gas out in all directions. Any zombies that are covered in the gas will become confused and start to attack other zombies instead of you. You can tell which ones are under influence if they have a blue glow surrounding them.
Stealth Bomber [125 kills]
A huge stealth bomber plane flies over the map and drops tons of bombs on unsuspecting zombies. You'll be able to control the position and direction of the strike before the plane takes off.
AC130 [175 kills]
If you get this far, I give you major props! You'll be extremely happy with this reward because you'll be able to control an AC130 attack plane from high above the map. On the AC130 there are 3 different weapon types that you can cycle through. You'll be able to use the plane for 40 seconds long. How much carnage can you tear up before your time is up? It will use the "viewport" object to zoom in and out of the level and maybe rotate the screen as well?
Rescue Signal Flare [200 kills]
Some people may get bored of a game that never ends, but wait! Does it end? If you miraculously get 200 kills in a row you'll be able to place down a signal flare that will alert your air support. Three precision air strikes will fly over the map bombing everything to hell, and then a rescue helicopter will come and rescue you which will end the game! If you actually get this reward you'll gain a huge point bonus plus all the points from the air strike carnage before!
Note: Your sentry guns DO help aid you in racking up the kills for your next streak. If you die, you'll have to start all over again from kill #1.
