Make sure to do a clean install (remove all old files and then install the new version).
The main reason it's like this is because the Navigation Mesh has square sized navigation areas aligned to the world grid (https://developer.valvesoftware.com/wiki/Navigation_Meshes). Placed buildings would break these areas in a weird way. Unless we replace it, I don't think it's acceptable or worth it to have large rotable buildings.
Validate Alien Swarm files in Steam.
Try adding one of the following commands to your launch parameters:
-disablecef (the main menu won't be shown in this case, but it's interesting to see if it loads without error)
There's an article about it on Steam Support KB: Support.steampowered.com
Note however your system is below the minimum requirements for Alien Swarm (and the requirements for Lambda Wars will be a bit higher too).
Can you give the exact error? Seems unlikely that's the message. Please also verify you can actually start Alien Swarm.
Sorry, I didn't build this release in a way that allows creating a patch. However, hopefully this will the last release before we publish it Steam.
1. This sounds like a bug.
2. Currently 2.3.5 has a bug which causes the Rebel CPU player to place too many barracks. The Rebel CPU also doesn't collect scrap yet, due which it does not place higher tier units. I hope to add this soon.
Can you provide some more information, like the video card you use and the settings you play on?
Make sure the file "sourcemods/lambdawars/gameinfo.txt" exists. If not, you likely created a sub folder structure like "sourcemods/lambdawars/lambdawars/gameinfo.txt". In that case, move the sub folder one folder up and restart Steam again.
In Sandbox mode you can control units, but it's more of an extra.
We will experiment with vehicles, but it does not have a very high priority.
Would be lots of work though (and editing brushes/terrain is pretty much out of the question). I want to focus on things which are hard/annoying to do in Hammer.
Do you know if it also happens in Alien Swarm?
Somewhere in the summer.
Not sure what you installed, but the mod is not available on Desura.
You are right. Last time I checked it was not possible. Changed it to HL2 Ep2.
ModDB does not allow changing the game on the mod profile.
Right now you need to own "HL2 Episode 2" on your Steam account and have Alien Swarm installed.
Look in the downloads, there's a patch version too for this release.
I will look into providing a patch for the next release.
You can still play the Antlion Faction in Sandbox mode. Balancing the Antlion faction in Annihilation mode would be too much work at this point.
Correct. It should try to install Alien Swarm automatically anyway when you try to launch the mod.
I guess we might add someone later to push them. For now they are just magically thrown in a direction :)
Alien Swarm is free. Currently it does require Ep 2, but that wouldn't change if we switched to SDK 2013.
Even though that engine branch is a newer release, it does not support all (engine) features the Alien Swarm engine supports.
This is not something on our side. The 7z archive should be used for installing.
I just contacted Desura support again to either remove the mod from Desura or fix their bugged client (since they clearly don't care about supporting mods).
Maybe you can provide some screenshots and/or console log?
