Just to let you know, Exodus From The Earth has broken links. To see this, go to it's page at http://legendsworld.net/shooter/game/1189, if you click on the 'DVD ISO Demo 2.74GB (uploaded by scaryfun)' download, then when you click on '1' then when the 4Shared page opens, it has four pages, listed 1 to 4, full of links (62 files in total), but when you try to go to the second page on the 4Shared page, then you just get a page with no files.
But it turns out the game is available at http://igg-games.com/exodus-from-the-earth-free-download.html, and in only two files, as opposed to the 62 files that are (or were) on 4Shared, so it's much easier to download from there.
