For those of you with proper video cards that do not have difficulty with precipitation scripts, here is a merged map of the scenario with both precipitation and the latest bugfixes.
Unfortunately, some quirk of a few people's machines - which I suspect were running integrated graphics - couldn't cope with precipitation, even after bugfixes were made, and so Pfhorrest ordered it cut from final release. Although the effect on most levels is subtle due to an A1 limitation on having 1024 objects, I thought it well worth the effort of maintaining. So, before I cut the lua from the main scenario, I created a branch to preserve it, and left the supporting alterations to the Shapes file in the main branch.
Naturally, you'll need to download Eternal 1.2, found here,, to use this map.
Then, download this map file, drop it in your Eternal directory, and select it in Environment preferences.
To test whether your machine can handle this, skip to level 13: A Friend in Need, and see if your framerate drops when you walk outside. My 12 year old rig gets 20 FPS with everything on, but some players have reported as little as 0.5 FPS with precipitation.
Since this is an altered map and not a plugin, it will not be compatible with save games from the official release or the previous 1.2.0 version of this enhanced map.
Co-op players, please ensure that everyone has the same version of the map.

Made a number of things a lot easier
This map pack is a redux version of the Legends of Marathon netmaps. This is currently the only set of netmaps made for Eternal. This will need to be played in the latest version of Eternal. Most of these maps were made for 2-8 players, and most work well in survival mode. Huge thanks to Spooky, Ravenshining, Pfhorrest, and Aaron. Without them, none of this would be possible. This set of maps is dedicated to the entire Marathon community, so do not feel bad if you do not have a map named after you.
original release
The President's Eternal Shapes
This is an edited Eternal X v110b3 Shapes file. It replaces some of the Marine bitmaps with new ones that match the weapon being held.
Messed with some color tables in EVIL to get the Marine's Pfhor Staff graphics, and also a less pixellated version of the weapon's item graphic.
Replaced the Havoc Rifle's grenade clip item with a cleaner version.
Both the Napalm Canister's and the Pistol Clip's bitmaps have smoother ones in their place, though I don't think they were used.
Added 3 new bitmaps to the Nightmare sequences. It can now appear diagonally from behind.
Changed the colors of the Pfhor Staff water scenery item to match the monster's theme. I'm not sure if this was used in the game, though.
Experimental. Changed the color of one of the alien scenery lamps (The one that looks like a staff crystal) to match the Pfhor Staff's. NOTE: Two files are included in this folder. The one marked with a * contains the latter changes. Try them both and see what you think.
