Seeing audiogames.net is an English website, the majority of discussion concentrates around games that are available in English. This means that many games can go undiscovered for a long time. Thanks to the awesome work by Mega Dimensão's, you can now experience Desafio Mortal in English.
The game is a side-scrolling MMO life simulator with a large world to explore and a lot of things to do. Explore the school playground and staff room, go out into the street to grab a quick snack, drop by the shopping mall to pick up a grenade launcher and some clothes, take a dive in the swimming pool, and go out into the unprotected areas to duke it out with other players using a verioty of weapons to gain experience and money. If it's not the middle of the night in game time and you make enough money, head to the police station, get a passport and fly to other cities in the game that feature their own items and a a different currency. While you're there, you can use the public train system as well as buy a house for yourself which you can then decorate. You can use this house to hang out with your friends, which can be a very awesome experience considering the game offers audio socials, the ability to make teams, private and public text chat as well as voice chat with people in the same room.
If you'd like to find out more, get a copy and talk to the developers, just take a look at this forum thread. Starting out can be hard, but if you get past the first 20 minutes of confusion I can personally say you will be rewarded!
