What if everything that went wrong on "A Red Letter Day" was not caused by what you thought? What if your teleport ripped a hole in space and time? Now you must travel through time to correct the events and set right your past.

Causality Effect has been updated. I have fixed and changed little bugs found in the mod after its release. In other news the mod will be aired in PC Games magizine this month and will be on a DVD disc that comes with your magizine.

I tried with all weapons. Didn't work. I did her in with the crow bar. It took a bit. I was almost out of health when she went down.

Seems the latest version has not fixed this bug yet. I remember playing this last year, got stuck with the queen, downloaded this 'new' version and still the same problem :(

I think one of valves many mod killing patches, has ruined yet ANOTHER great mod.

Flying-Q's comment below, mentions that there is a screenshot where the player is positioned on the other side of the bars that trap you with the queen, and there's a hole in it.

I’m guessing there's some kind of scripted event that’s supposed to take place where the queen rips open the bars, and the creator of the mod made the queen invincible until that event took place so you couldn't kill it and trap your self.

If this is true, then the scripted event was probably broken by a valve patch, in which case we need someone to fix it.

I’m going to try and contact the mod author about this...

I am having the EXACT same problem! I can't kill the queen, and theres no where else to go. I can't find any entrances, passages, exits, or anything to continue onto the next area, and the queen will NOT die! I must have thrown 5 barrels, 3 rockets, 5 grenades, 2 mortars, and all my ammo... nothing will kill it....

What am I supposed to do? I see no consoles I can use or anything I can interact with! Can someone please help??

Also stuck at the ant lion queen in the sewers. Tried normal weapons/barrels, tried making it run into the fire, tried making it run into walls, etc. It assisted me in getting onto the ledge on the left, but the door is locked. What's next?

This is the second mod I've tried and it was superb.

If you're reading this and are considering it to download...its definitely worth it.

Best bit: The graveyard battle

Scariest bit: Combination of creepy cooridor, flickering light and fast Zombie

Annoying bit: Slow and frequent loads.

Frustrating bit: reaching the end...I was ready for more.

All made by one bloke.......good work fella....Valve should give you a job!
