Make a number of 4shared accounts. Depending on how many games you intend to download and their size, you might want anywhere from 2 to 50 (if you're an overachiever trying to download everything you possibly can). This isn't a fun process, as you have to constantly bounce back and forth beween creating an email account and then a 4shared account, then back to the email account to activate the authentication email. Both Yahoo! (I don't actually use Yahoo!, but it's probably the easiest site to make email accounts for, so keep that in mind) and 4shared even gave me messages along the lines of, "Why the shit are you making so many accounts, you freako? That's mighty damned suspicious. -_-" which is nothing more than tiny lil' baby hindrance as 4shared makes you enter in a quick captcha. It's amusing, though, but that's beside the point.

Milk the everloving hell out of each account per day. This is where the real 'tactics' come in. 4shared is kind of strange in how it manages detection of the amount of data you've downloaded. It seems to only update the amount of data you've updated when a file finishes. However, you can only keep up a certain number of downloads at a time (or it's possibly limited to how much data you're attempting to download at once, which seems less likely, but I'd need to pay close attention. I'll edit this post if I notice anything along these lines). This means you need to do some math sometimes. Yeah, I know, that sounds real damned fun, but it's a lot better than having to wait until the next day because you cut yourself short on each of your accounts and can't download anymore.
To be quick about it, pay attention to the size of the .rar files you're probably downloading. Keep this in mind. Then figure out how many of those you can download while still leaving room for one of these files to be downloaded. If you're downloading a hell of a lot of smaller files, figure out how many you can download while leaving room for 3 or 4 of the files to be downloaded. When you've figured that out, download that number of files and let them finish downloading. You should still under 3 GB with room to spare for one or two 100 or 200MB downloads, or three or four 25MB downloads (or even five or six for 12 mb downloads. Also, this is off-topic, but please stop uploading games in a billion tiny pieces, people. 100 MB or 200 MB files are GODSENDS and even those seem too small sometimes when there's 80+ files to download on larger games). Now, if you aren't using the folder view of 4shared, you might want to. It has a bug at the moment in which it doesn't wish to display the last page of files unless it's a full page, but there are several ways around that. I suggest the folder view because it's easier to just bring up a number of tabs at one time. With there now an appropriate amount of space available for more downloads, bring up around 18 - 20 tabs of files of the game you're trying to download. If you end up going to another page to grab more downloads, don't do so quite yet. If all of your downloads are on the same page, do what I'm about to say regardless. Go on each tab and click 'download'. It will reload the page and it will display 'FREE DOWNLOAD' as a grey button with 'Waiting time - 20 seconds' above it. Don't click that yet. Just get to this page on each of these tabs. If you still have more tabs to fill, NOW go to the next page and grab the rest. Then do the same as you just did, hitting 'download', but NOT 'FREE DOWNLOAD'. Verify that each tab is on the appropriate page. Now, go to the first tab in this new Congo line of file downloads you've lined up and get ready to be quick as hell. When you're ready, you're going to click 'FREE DOWNLOAD' to set the timer ticking down. Then go from tab to tab, clicking that button to set up as many downloads into motion as you can. Don't worry if some files start to download, just be fast enough to get the timers counting down on all of the pages before you've filled up your remaining 3GB download limit.
If you've done it right, you've now got something like 20 (more or less) downloads running at once. If some of your pages aren't loading over to the page that says 'Your download has started', you've probably hit whatever potential download limit (not the same as the 3GB limit I've mentioned, as that will give you another message stating that you've reached your daily 3GB limit in that case) they have in place and it'll start when one of the other downloads finish. Through this way, I've managed to download over twice, nearing 3 times the 3GB limit on some games with larger files. When all of your downloads finish (some may not have started if you're unlucky or too slow, and they'll have a "You've reached your limit" message for you to see), switch to your next account and restart the process.

Yeah, so this was a long and potentially confusing(?) post. If you need any clarification with screenshots or the like, just ask and I'll clear it up. I'm tired and I'm sure I made grammatical and spelling errors as well as just generally writing in a rough, hard-to-understand way. I'm not great at communicating.
