Punctuation Invaders

Punctuation Invaders is a fun and challenging arcade game that serves as a useful tool for practicing grammar skills. The game puts players up against extraterrestrial invaders in the form of unpunctuated, uncapitalized sentences. To defeat the aliens, the player must fire a laser to punctuate each word in the sentence while avoiding incoming shots from the alien ships.

However, it's not just about punctuating words - the sentence must be completed before the aliens get too close and beam up a human. What makes Punctuation Invaders stand out from other educational games is its real arcade game play complete with fun interactions, sounds, and background music that you'd expect from a classic arcade game. With three difficulty settings, the game caters to players of all skill levels, from very easy to quite challenging.

Moreover, players get to select their difficulty level, as the difficulty of the content depends on the file chosen. The interface presents a full-screen (at 800x600) arcade setting that provides the complete gaming experience. The game's exercises push students to consider a wide range of possibilities and place many instances of punctuation before receiving feedback.

To run this game, you need a screen resolution of 800x600 or higher and at least 32MB of memory installed, depending on the operating system. However, the unregistered version of Punctuation Invaders only allows players to access the Demo & Training level of the game. Overall, Punctuation Invaders is a unique educational game that combines the best of arcade experience with grammar practice.
