This script adds some basic quality-of-life improvements to Marathon's default cooperative play:

• Shares weapon and ammo pickups between players
• Restores previous weapons and ammoes after respawning
• Respawns players at the last pattern buffer any player activated
• If the respawn point is under lava or goo, falls back to start of level

Select "Use Netscript" while gathering a co-op game, and choose Basic Co-op.lua as the netscript, to activate it.

Requires Aleph One 1.3

Notes for version 1.2:

Changes:

• Really fixes chip issues. Should work with original Marathon as well
• Uses the last pattern buffer any player used as the new respawn point.
• Falls back to start of level if the respawn point is under lava or goo

Here it is, at last: Marathon TROJAN. Now compatible with Aleph One (1.3 or newer), this uses the native M1 files to deliver the original, unaltered experience we know from the 90's.

M1 compatible fullscreen HUD plugins will work with TROJAN if you don't want to use the included Classic HUD plugin.

Additional files include the Weapons Pump Patch, FAQ, Manual, Spoiler Guide, and read me's from older versions of TROJAN.

Special thank you to Hamish Sanderson for giving us permission to distribute this re-release of TROJAN. Enjoy!

Update 3/3/25 - You can also find a Trojan standalone edition here https://hhas01.itch.io/trojan-se

"James’ Trojan AO scenario (2020) is a highly faithful warts-n-all port of the original M1 Trojan. This was important for historical preservation of early Marathon history, but not a great gameplay experience itself.

Trojan Standalone Edition (2021) made numerous fixes and enhancements to James’ scenario and customizations to the engine code. That’s why it’s released as Standalone Edition, not an add-on."

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.

Notes for version beta 1.1:

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

"A 19-level solo masterpiece, with new sounds, shapes, terms, physics, bobs... and it's totally non-linear (you decide what order to do the levels in). Brought to you by the folks who did U.S.S. Raider, Athens Outpost, and the Marathon's Story page."

This scenario has been converted to an Aleph One compatible format and repackaged for Simplici7y.

This is a small, symmetrical netmap supporting emfh, koth, ktmwtb and survival. It has been merged with Hopper's Aleph One Previous AI to prevent monsters from freezing up, so the plugin won't be necessary for this map. It's recommended for two-player sized netgames, but three might work aswell.

At MacWorld 1996, Power Computing (a popular Macintosh clone manufacturer in the mid-1990’s) released a CD-ROM called “PowerComputing The Disc 2”.

This contained a special demo of Marathon 2. Instead of the normal sprites for Bob, there was instead special sprites of the Director of Evangelism of Power Computing, Bob LeVitus. Also included with the demo was a Shapes file that could be used with the full version of the game.
I was surprised that this wasn't already ported to Aleph One so, I've rectified that.

This is a version of the Marathon 1 Hd Weapons Pack that has been made compatible with the old M1A1 release.

As such, this will not work with current versions of aleph one, using the original files.

All credit for making this compatible with M1A1 goes to to Thedoctor45.

POWERS is a new kind of Marathon gameplay. Instead of having an arsenal of weapons, the player carries only what is inside his mind—his POWERS.

POWERS works under Aleph One with any Marathon scenario, and, in theory, any game type. However, the best way to use your new POWERS is with a friend in Co-op mode! New challenges await you in your favorite levels, and you might find that your POWERS even enhance levels you never appreciated before. Just use the POWERS Lua script when you play!

Notes for version 3.0.1:

Total overhaul. See the Readme.

Better Bridges is a new technique for simulating bridges in Aleph One levels as if the engine supported them natively. It’s a generalized Lua script that can work with any level that’s set up in a specific way. Included is a guide explaining how to make maps with Better Bridges, and a working sample map.

Ryoko asked me to re-create the "Arms Race" game type from Counterstrike in Aleph One. Here's my attempt.

From the man himself:

Basically it's an EMFH script where everyone starts with rockets, and after each kill you get demoted to a weaker weapon, and the winner is the first person to get a kill with fists.

A plugin for the original weapons-in-hand graphics for Aleph One, featuring: - Different looking muzzle flash with blended edges. - Motion blur on certain frames, including bullet shells and the fists. - An optional translucent scope effect for the magnum.

Works with both Marathon 2 and Marathon Infinity!

Notes for version 1.5:

• Removed black halo around edges of the optional graphics for the Marathon 2 SMG.
• Optional graphics for the Marathon 2 SMG have been made powers of 2.

This is an English translation of the Aleph One scenario "Blauwe Vingers", originally in Dutch. All due credit for the original scenario and game content belongs to Tim Vogel and Stage Game Studio. The translation was the combined effort of myself, Drictelt, and Google's translation service.

This is a translation of the map file only, which means only terminal text, map text, level names, and console text are translated. Everything else, like interface text, loading screen text, and audio, is unchanged at this time.

To install, move Kaart.sceA into the "Data" subfolder of your Blauwe Vingers installation. For more information, see the included read me file.

Enjoy!

Notes for version 1.2 English:

This is the first release, compatible with Blauwe Vingers 1.2.

This Aleph One plugin allows you to go under water calmly without having to look at those heinous faders. It works great for texturing liquid maps with Visual Mode by treellama, and is compatible with Marathon 2, Marathon Infinity and other plugins.

This Lua script introduces a number of changes and tweaks in the mechanics of co-operative games. Version 2 has a number of improvements thanks to the new Lua API found in Aleph One v0.20.

See the Readme file for a whole lot more detail.

Notes for version 2.2:

Added a few minor changes, including one that allows the script to work with the post-1.0 betas.

This script is a revised version of Iamanidiot123's advanced cheats script, which is based on the original Cheats.lua released by Treellama in the Aleph One download. I have added some additional functions including hard falling damage.

Some of the functions included, like the invincibility modes, and teleportation are intended to be used for recreational solo play or the testing and debugging of maps or scenarios. Others are intended to add additional features, like the ability to heal, or falling damage. Please see the included readme file for important information.

Notes for version 2.7E:

Same as 2.7D except I fixed a typo that prevented the use of the script. Everything else is same as 2.7D.

Improvements to this version include additions to the overlay function to display the oxygen level in blue and the energy levels in red, yellow, or dark red [I haven't been able to get purple yet] depending on the energy levels.

More detailed information is included in the readme.txt file

To those who don't seem to bother actually looking at the readme or code, the first few lines of both are acknowledging the work that both TreeLlama and Iamanidiot123 did, both of whose versions are included intact with their original readmes.

A short solo map which was originally meant to be for KTA IV, but got a bit too big for the requirement, so instead of going to waste I finished it.

This will be the first time where I've used all the tools required to make a map with Aleph One.

EasyShade contains functions for automating the lighting of Aleph One levels. It is intended to aid mapmakers in conjunction with their usual lighting techniques. EasyShade currently includes these functions (all parameters are optional):

sunlight(contrast, manual\_sun\_angle, cumulative) for simulating a directional light source that affects all surfaces and does not cast shadows

roomlight(brightness, floor\_threshold, ceiling\_threshold, radius) for assigning a brightness to an entire room at once

pointlight(brightness, max\_radius) for simulating a point light source where the player is standing (calculations done in 2D)

darken() and lighten() for nudging the brightness of the room you're in up or down. These functions are tied to the previous and next weapon keys, so you can make an adjustment by pressing one key instead of typing out a function call.

pavelight(brightness) for applying a single brightness to all surfaces in the entire level

resetlights() for restoring a level to its original lighting levels

Notes for version 1.5:

Major update, now with wholly different types of automated lighting.
