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.

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!

This mod has an excellent sense of pace, scale and imagination. I played it all the way through immediatly after installing it. I think I enjoyed it more than HL2 itself! It combines story line with action in a well balanced cocktail that keeps you pushing on. A few simple puzzles serve to slow the game before launching you into the best HL2 fire-fights I have been involved in. It captures that old school 'boss' feeling in the set-pieces, particularly at the end, and multiple endings inspire you to play it through again. Not to mention the slightly tongue in cheek humour :) All round one of the best mods I have played ever. And done by one guy... ?!

Anyone for a free HL2 expansion pack?!?! Hit the download tab!

"Thanks for the Mod" is all I can say.
