Eng Zombie is a free Android game that combines vocabulary learning and zombie-killing in one. The game includes basic vocabulary frequently used in everyday life, making it suitable for Thai people who are not good at English but want to learn. The vocabulary has been selected from the first 1500 most frequently used words, so beginners don't have to memorize words that are not commonly used.

The game is designed to make vocabulary learning more engaging and less boring. Instead of memorizing words in an old-fashioned way, players can recite vocabulary and kill zombies at the same time. The ranking system measures who can kill the most zombies, so players can invite their friends to compete and see who will be the king of killing zombies. Overall, Eng Zombie is a fun and effective way to learn basic English vocabulary.
