Ubisoft has at least three Tom Clancy games in development, so the time is right to set all the older ones free. While not strictly 'free', you can grab a huge selection of Tom Clancy games in the latest Humble Bundle sale, while also securing access to the forthcoming Rainbow Six: Siege multiplayer beta.
The bundle includes the original Rainbow Six, Rainbox Six 3 Gold, Rainbow Six: Vegas, Splinter Cell: Chaos Theory and Ghost Recon – as well as the aforementioned beta access. If you pay above the average (which at the time of writing is a measly $7.78) you also get Rainbow Six: Vegas 2, Splinter Cell: Conviction and the original Splinter Cell, with more to be revealed.
Meanwhile, if you pay more than $10 you get Ghost Recon: Future Soldier and Splinter Cell: Blacklist.
Phew! That's ten Tom Clancy games! You'll never want to play another one again. Until next year that is: after Siege releases this November, we've still got The Division and Ghost Recon: Wildlands to get.
