Whilst these new weekly Humble Bundle deals might lack pizazz of the main bundles, they're still a great way to pick up some games for a few dollars. This week, it's the turn of Tripwire Interactive to be included in the Humble Bundle.
For just $1, you can get the World War II multiplayer shooter Red Orchestra and its sequel Heroes of Stalingrad. If you beat the average (just $2.85 at the time of writing) you'll also pick up the co-op zombie shooter Killing Floor too. Not all the games are available on a mixture of Windows, Mac, and Linux so make sure you check the game you want is available on your format of choice.
All games come with plenty of DLC and soundtracks so if you're in the mood for some multiplayer fun, then these games are a steal at this price. I've spent dozens of hours playing Killing Floor with friends and can't recommend it highly enough if you love co-op games. Remember, you're money is also going towards the EFF and Child's Play too, so why not splash out?
