Because the enemies come in great numbers, your character can die really quick if you are not careful. For moving in the game you can use the keys A and D and for jumping you use W and R for reloading. For looking and shooting you can use the mouse. There are different types of zombies, as some can be slower and they have to get closer to you for causing you damage. Other types of zombies can spray you with acid from a distance. Make sure you kill them first. Stinky beans can be of two types. Some of them explode when they touch you, so make sure you avoid them. If you want to get a higher score, you have to kill enemies through head shots and center mass shots. First aid kids are meant for healing you completely. In all the versions of the game you have the same simple objectives: run around carrying your weapons and kill all the enemies. Thing Thing Arena is easy and fun to play and you can invite your friends to play too, as this can motivate you to beat their score and get a higher score for yourself.
