That's how many days in a row you played. Max is 5.
After losing a tail mark, you need to reach 15 rounds one time to return it. One tail mark can be returned each day.
You will lose a taily mark if you don't play any match in 24 hours.

You start with this rank.

First mission - Get +500 kills. If you get 500 kills with large down count and fail to rank up;
Second mission - Get +1000 kills.

First mission - Reach 50+ K.D. before 3,000 kills. If you fail;
Second mission - Reach 4,000 kills

First mission - Reach 140+ K.D. after 15,000 kills. If you fail;
Second mission - Reach 120+ K.D. before 20,000 kills. If you fail;
Third mission - Reach 80+ K.D. after 20,000 kills.
If you fail all 3 missions, then just get 80 K.D. and you should rank up.
If you are not promoted to next rank after completing third mission, then try to reach a high round (20, 30, 40)

First mission - Get minimum 150.00 K.D.


Second mission - Play alot. With the best stats, even 400+ KD, you wont achieve shotguns if you're not active.



You don't need to play TranZit, you can rank up even with playing Town or Farm only.
Normaly, after 40,000 kills you start to gain higher and higher chances to advance to this rank.

SPAWN.

You are spawned. Wait for zombies to appear and let them enter the nuketown ground then shoot 6 bullets from M1911 to their body and then knife them (10+10+10+10+10+10+130 = 190 points). At the end of round 1, you will have 4 bullets left in M1911. Now go to the back of the yellow school bus and buy M14 off the wall (500 points, 250 points for ammo). At round two, shoot 1 bullet from M14 to their body and then knife them. At round three, shoot 2 bullets from M14 to their body and then knife them. The number of your current round shows you how much hits it requires to kill a zombie with M14 so if you are on eg. on round 5, you go shoot them 4 times with M14 to their body and then knife them. The knife is 5th hit so they die and gets you more points than you actually get from killing them with a weapon.

REACHING THE TRAINING SPOT

Remember, you will always have 4000 points on round 4 or 5. Depends if you got a nuke or not. And always open the doors of the green house (750 points) NO MATHER IF THE MYSTERY BOX IS OR NOT THERE, then right away open the next doors (1000 points).
NOTE: The green house is the house with B23R pistol and Fallout Shelter in the garden.
Now that you reached the training spot, train some zombies and headshot them with M14 because it will become harder after each round to knife them.
IF THE BOX IS IN THAT GARDEN: Use it.
IF THE BOX ISN'T IN THAT GARDEN: Wait til you reach 6000 points, leave a crawler and open both doors in the yellow house (750 & 1000 points) then try to get desired weapon.

PERKS, WEAPON-COMBINATION, PACK A PUNCH, CLAYMORES

You have no perks atm. Only quick revive if you've bought it. Now do not get any perk such as Speed Cola, Double-Tap because it will be waste since you get the same chance to be downed and then you will have to buy them all over by wasting extra 5000 points. Wait until juggernog falls down the ground then buy them all at the same time.

The best weapon combination and most used is Ray Gun and Mustang&Sally. If you consider going to headshots and hit accuracy then go for LSAT/RPD and Ray Gun. I don't recommend HAMR because it has very low accuracy and bullets just like... fly all over even with aiming down sights not to mention firing from the hip, smh. You can go with LSAT/RPD and Mustang&Sally if you still want headshots and hit accuracy but with less risk of being trapped and if you change your mind to go for high rounds since Mustang&Sally cleans a huge horde of zombies within few shots.

Pack a punch a ray gun (if you r goin for it) when you run out of it's ammo (thats what Syndicate does) so you don't have to wait max ammo and in case to instantly earn 40/200 ammo in it, and that there's not a huge difference between Ray Gun and Porter X2's RG damage.

Get claymores and semtex as soon as possible (will cost you 3000 points opening the doors aswell, it's in the truck) and everytime at the end of round if you still have them, put them infront of the Fallout Shelter (max 12, 13th will instant explode) so anytime at highrounds you run out of claymores you can just pick them off the floor (They won't explode, not even if you shoot at them, only if you put it infront of zombie(s))

Double tap gives you extra damage (video is above) and alot higher fire rate (you all know it already).

Now that you are fully armored and ready to kill them, open debris (1250 points, located in the green house's garden, stairs) so when you're overnumbered you just sprint upstairs then jump down.

Get galvaknuckles when you're full of points.
