LW News! (Week 6)

Hello Strategists!

Man, another slow school (or work) week for us all, right?
Well, for those of you celebrating, Happy Early Thanksgiving! And those of you that just want this year to be finished, Happy HallowThanksMas!

Now, onto business. Sadly, the development crops haven't dropped ripened fruit quite yet, but we have our oh-so beloved Dr. Mad looking at units, and deciding what entirely needs balancing and such.

Luckily for us, our beloved slave Mr. Darkness is finishing up his real life stuff (Gross, I know) and will be back to hs "90 Hours a Week and Loving It".


P.S. - Please stop asking about New Races, PLEASE. We've said 5 too many times that there are NO plans to add any new races to the game. Thank you.

P.P.S - First to tell me which movie I referenced with the line "90 Hours a Week and Loving It" will get bonus points.

Engine errors?

Hey guys.

Recently I heard a number of you peeps are getting the following:
Engine Error - "Could not load library client"

If this seems familiar to any of you, please make sure you're:

  • Not running Windows XP. It's no longer supported. Vista users crash a lot, according to our minidumps.
  • Launching a fresh download of the game OR have just recently updated, became unable to play while previously were able to launch the game before.
  • Didn't fiddle with the game library on your own without knowing exactly what you're doing or haven't followed a developer's instructions. The game library is located under Steam/steamapps/common/Lambda Wars

Keep in mind that the game launches alright for us devs and majority of players, so it must be something to do with your system specs or the file system. This is something I'm trying to look into right now.

Please leave your reports either in the comment section, discussions or contact me through either Discord or VK.
