The bonus ticks from going offline should accurately reflect the time you spend offline. I got 2 hours of bonus ticks from being offline for 8 hours, which is unreasonable. Even if you don't make it the same, just make sure that you get like 3/4 of the ticks instead of only 1/4
The most important item for new players is the radio. You will find it just like ammo and medical items, it's just rare. When you use the radio, a package will drop from the sky, it will flash red, and then a black box will appear on the ground. Inside you will probably find flares or glowsticks (essential for surviving the night), and a good weapon, which you will need to find ammo for.
Another tip: its important to have a flashlight so you can travel around at night and find ammunition and other items. The flashlight is a great investment (only $500), and so is a flare or glowstick. If you don't have a flashlight, flare, or glowstick, there is no point in spending the night and waiting it out. Its better to quit the game, collect your cash, and start over. New waves won't spawn until you have killed most of the previous wave, and at night there are usually zombies in random locations, which cannot be found without a flashlight, glowstick, or flare.
if lvl 5 is the one with two 3 gallon tanks, the objectiveis to build a circle of pipes around the tank. Get a and attach it to the 3 gallon tank on left. Make sure the pipe makes the water go left. Then do the same thing on the tank on the right, but make the pipe point right. Then put a 2 gallon( the one that holds 2 gallons then empties the rest). Then connect a pipe to there pointing left. Then connect all the pipes except the 2 gallon tank, to go around and over the top of the 3 gallon tanks.then put the last 2 gallon tank to the right of the first pipe i said to put in.
