-When you first begin the game - in the opening tutorial - you may notice there aren't many humans to infect. Don't worry. During your second run, you'll see a few more. Try to collect them all in one shot if you can, because the more humans you infect, the longer you keep the run going.
-Upgrade, upgrade, upgrade! Like Jetpack Joyride, Infectonator: Hot Chase has a number of coins to collect, either sitting in piles on the street or "pickpocketed" from humans you infect. You can turn these around to improve your zombie's performance. The most important ones are Max Horde, which can increase the number of zombies you collect on each stage; Mutation Chance, which scatters more power-ups on each stage; Speed and Stamina. You'll have plenty of chances to upgrade, and once the in-game store begins working again, you can buy extra coins - completely optional, of course.
-Watch out for power-ups. These are glowing green orbs that appear throughout each stage that grant access to a number of characters. Our particular favorite is the Bomber, who you can detonate when surrounded by humans, so you can infect them all in a single blast. Each one is quite helpful, though, including the Bolt, who gives you a much-needed boost of energy; the Puker, which shoots projectiles ahead of you to infect out-of-reach humans; and others.
-There are several unlockable zombies in the game, each with a certain advantage. You've got the Kid Zombie, who can move up and down the screen faster; the Gangster Zombie, who runs on a motorcycle at an increase of 40 percent speed; and more. They require a higher coin count, so if you're going to put down real money, invest in these guys.
-You receive one speed boost at the start of the level, but don't waste it! Instead, try to save it for the later part of the stage, like when you're starting to run low on energy. If you can, use it when you get to the first police barricade. You'll bust through without taking damage from bullets - which can affect your health - and continue on your way.
-They may seem useless, but be sure to check out the Trivia Tips on the recap screen. You'll learn a thing or two - like how Walt Disney was actually afraid of mice.
-Finally, be sure to unlock the Gangnam Zombie. Not only will you get a few laughs from his design (PSYYYYY!), but you'll also attract coins using a magnet, and earn double coin scores. He'll really clean up for you.
