The contents for September's bundle have just been revealed. The games are:

Killing Floor 2 (Early Unlock)
Banner Saga 2
Momodora: Reverie Under the Moonlight
Worms W.M.D.
Stories Untold
HackyZack
Eterium
Volantia: Kingdom in the Sky (Humble Original)

Next month's Early Unlock is Rise of the Tomb Raider.

I'm guessing it's just the base game thing. Most things on Humble Monthly tend to be.
Personally I've been considering getting HackyZack and Momodora so that's going to be interesting.
Eterium I believe was also slightly interesting to me. And Banner Saga 2 is, I believe, fairly well regarded.

Too bad Killing Floor 2, the top billing of the month, is a rather poor showing. From what I've played of it it's basically Killing Floor 1 with better graphics. Microtransactions and enemies which seem to be spongier than ever, almost makes me feel like I'm playing Borderlands with some of them.
Oh and several minutes to load into the game is just really discouraging me from booting it up to see if I'm missing something.

Pretty disappointing if true, don't want to risk taking next bundle unless it's the anniversary pack. A noob question but if I'm subscribed for 6 months can I skip a month in between and continue (Whatever number of months I've remaining) from the month after that?

No.

From posts on Twitter and Reddit, it seems to be just the base game.

The wife will be happy. She's just got around to finishing Tomb Raider and I missed a decent offer on the PS4 retail version. Hopefully the game won't lag too much over the Steam Link.

Agreed though that this month is rather shite. Killing Floor 2 is just there to boost the rather poor player numbers (as are MP shooters always).

I just subsribed last month and feel a bit let down with this month's offering too. Stories Untold is the pick of the bunch for me but I had it already...

Banner Saga 2? Cool!

Well, nothing in this one was interesting for me so good that I paused.

But Rise of the Tomb Raider... mmm, I kinda want that, really enjoyed Tomb Raider reboot even if there was too much shooting at some points... hmm... it will be another hard decision :)

Rise is alot less button mashing than the 2013 version. But theres things it does better and worse. If your tempted the take this into account, whilst every machine is different, it went from running great maxed out to badly with the 20th Anniversary update and since.

Theres still a fair amout of shooting though,but there is more puzzles and tight jumping.

Yea, it's really tempting but I will have to think (after all, there is Divinity OS 2 coming out this month and Elex next month), thankfully I have whole month to do that. :P

It's a fantastic game and the best looking game around in my opinion - absolutely stunning!

Yeah, I did some research and I only want it more now but, well.... I will see how this month will go for me. :)

Seems my post on the subject disappeared...

Anyways, Humble has Walking Dead season 1 free for 1 day, steam key only. For those that are interested. I won't post link in case this gets removed as well.
