Zombie Army Trilogy

*ONLINE REQUIRED*

You can do this alone in an private online game, but it is best done with at least one other player who you know. Make a private game, invite your friend, and have difficulty as 'Cadet' with '1-player' enemy spawns. You can try making a public game the same way if you get lucky enough to be the host. 

For the high score and most medals, you can always have the friend leave your game if you need him to (assuming you are host) then the friend can re-join the game with a fresh zero counter on everything or take turns on different maps handling the majority of the zombies.

The medals are awarded for best shot, most kills, most revives and highest combo (multiplier).

If alone for high score you just need to maintain a high combo multiplier, the higher the combo the more points per kill. *Missing a shot will lose the combo.*

Best Shot:
This is calculated by how high a score you obtained with one single bullet, take a high velocity rifle now what you need to do is build a massive combo up. Each combo increases the points you gain per kill, the basic kill on a body shot is 10 with a x40 combo this would be 400, what you want to aim to do is have a massive combo count and then get a multi-kill with a single shot. So build a combo then look for a train of zombies behind each other and try score a nice multi-kill with a single bullet.

Most Kills:
Self explanatory, get the most kills, know the explosive items locations around maps, try to use up as many as you can quickly to get that kills boost and to make it more difficult for others to gain massive kill streaks.

Most Revives:
Self explanatory, remember to revive team-mates but don't dive into massive groups of enemy's or risk getting yourself knocked down. You have 60 seconds clear the zombies around the player, you can even throw an grenade on the player to brush away all the ones that killed him.

Highest Combo:
This goes hand in hand with best shot, just kill enemy's use explosives, don't miss shots.
