Almost Transparent Blue is a single level for Marathon Infinity with an emphasis on intense close quarters combat and creative use of Marathon's air movement.

I first began work on this level because I kept worrying about how the kind of combat I enjoyed would be received by the wider community. I created this level to indulge the kind of fight design I enjoy, where concepts like bullet herding and crowd manipulation come into play and the player is surrounded by enemies. Over time I decided I wanted to find the elements of challenge gameplay that are unique to Marathon's mechanics and aren't possible to recreate in other classic fps games.

If this understandably isn't appealing to you Easy and K should offer a relaxing experience for the most part.

Total Carnage is balanced for my enjoyment. Maybe you will enjoy it too :)

Due to a bug with raised dynamic limits, currently trying to load saves from this map after quitting the A1 application will crash A1. To fix this, begin a new game on the map, then exit to the main menu and load your save.

may require Aleph One 1.3 as I haven't tested with 1.2 and don't know when dynamic limits were changed. additionally software mode will experience some visual bugs with invisible liquids.

tweaked player starting position to make the jump to AR easier without straferunning, tweaked item placement in final area to give the player a better cue for when to shoot at the beginning, hopefully fixed a monster bugging out in the same area
