OMG HD Zombies! is an awesome reimagining of a genuine classic: the critically acclaimed OMG-Z, a Metacritic top-ten all-time PSP game. OMG HD Zombies! features completely redrawn HD graphics, more gore, more levels, more upgrades and all-new content including 12 trophies, 100+ leaderboards, a 20-stage "Prestige" system and 5 beautifully illustrated endings. Armed with your bare wit (and a large-calibre sniper rifle) your lone cop is the last man standing at the epicentre of the outbreak. Your mission? Succeed where the police and army failed, clean the streets of 8 different strains of bloodthirsty zombies and stop armageddon in its tracks! Use your sharpshooting chain reaction skills to vanquish 100 branching levels of zombie hell across 40 unique environments. Earn 400 shiny medals and cold hard cash, and use it to buy 100 different upgrades, all designed to MAKE HD ZOMBIES EXPLODE! Source: The Developer Website.
