If you're looking for some new team-orientated shooters to sink your teeth into, you might be glad to hear that Arma 3 and Day of Infamy are currently free to try out on Steam. The promotion will only last until Monday, however, so if you're interested you should go and start the download immediately in order to have enough time to actually play them.

As for whether they're any good not, I'm afraid I have no personal experience with them since these types of shooters aren't my cup of tea. That said, I have heard a great deal of praise about both games, and they are currently at 89% and 85% approval rating on Steam respectively, so if you're even remotely curious about tactical shooters it might be a good idea to give them a chance. After all, they're completely free for the time being!

And just for good measure, I'll leave you with brief trailers for both games. The first one is for Arma 3 and is fairly outdated at this point, but it should still give you a decent idea of what to expect. The second and more recent trailer is, naturally, for Day of Infamy. Enjoy, and don't forget that the free weekend will end on Monday!
