This mod drastically changes the gameplay of Marathon!

Combat is much more fierce. This is like Marathon on steroids. Experience it for yourself.

*This mod establishes a new oxygen system: - You start with 2 minutes worth of oxygen (average human breath time.) -When you go into an environment in which you cannot breathe, you will start holding your breath. Be careful you don't black out! Holding your breath for too long makes you delirious, you know. - Luckily, if you make it to air in time, you can catch your breath and get those 2 minutes of air back. - Oxygen tanks now add tank oxygen to your total air capacity. When your tanks run out, you start holding your breath.

• It is also possible to become delirious from being in a near death state.

• Monsters and weapons are now more accurate and lethal, and travel at high speeds much closer to reality.

• Physics are changed, especially gravity, which is more realistically amplified from the low-grav Marathon stock physics. NOTE: this may make some jumping puzzles unsolvable. Gravity has been changed to closely match that of Earth (on standard gravity maps).

Notes for version 1.0:

This can certainly be improved upon, but for now, it's stable and it works.

This shapes, sounds, and physics pack is designed to make the play of Marathon Infinity more realistic. In future, I may modify even more of the game's workings, such as monster movement speeds or attack speeds.

NOTE: This physics model is not designed for multiplayer use; it would make the weapons incredibly overpowered and many maps almost unplayable.

Notes for version 2.0:

A comprehensive list of changes can be found in the Read-me file.

This is a simple physics file that uses a modified version of the physics file found merged into the level "You Think You're Big Time? You're Gonna Die Big Time!". This "project" initially began as a way to humor myself but I found out that it is actually lots of fun to play around with using the Survival game type, so I began trimming stats until I was happy with the difficulty.

For the most part, all you need to know is-

Most enemies are now completely gray, good luck guessing rank between fighters! Major troopers and major hunters now drop x1 HP powerups Slight increase in enemy vitality across the board Slight increase in enemy projectile speed across the board Fighters move very quickly, troopers are more grenade happy, hunter projectiles now track their target (just like in YTYBT?YGDBT!)

The Pfhor have captured our dear Hero, and now the Hero must fight through the legendary commanders in the gladiatorial arena to earn freedom!

Lua scripting gives each boss phase a different flavor.

Found this in the "M1A1 Mapmaking Kit" in the Aleph One utilities section of the Battlecat's Litterbox.

I tried out each of M1 Map Dude's uploads with these and didn't have an issue.

Notes for version 77.7:

Merge this in your M1A1 maps.

This is just a quick physics file that I thought up in my sleep. It really amps up a lot of the weapons. Heres a description:

Pistols: Shoot Rockets

AR: Ultra Shotgun Attachment

Shotguns: 2 shots per shell

Alien weapon: Shoots Shpt'Kr Bolts (2nd trigger major)

SMG: 100 round clip

Flamethrower: Normal

Rocket Launcher: Shoots Major Spht' Bolts

Fusion Pistol: Major Damage Increase (CAUTION: DO NOT SHOOT AT CLOSE RANGE!!!!)

That's about it. If you find any bugs, or have any suggestions, just leave me a comment.

Notes for version 1.0:

Careful of the fusion pistol because if you fire at close range it may lock up your computer. This has happened to me before.

A physics file to use together with visual mode lua. It stops the constant teleporting of enemies. It's universal and works the same on all scenarios. Enjoy a visual mode without distractions.

Notes for version 1.0:

No sounds or visual appearances are made by monsters.

No slowdowns detected on my machine (2ghz pc, 4gb ram, 256mb graphic card) when I ran through a 1024 polygon solo level and activated all monsters.

Yeah, jumping on the bandwagon here.

This pack includes 4 physics models: Destruction, Synergy, VacBob War and Vidmaster Physics. VacBob War has been seen on Simplici7y before (with an MML script to boot) but the other three have never seen daylight.

Destruction is a classic over-the-top superpower physics model, including such gems as a flamethrower Gatling gun (which mows down enemies like clam chowder) and a flechette blood sprayer, which is in just because it's awesome. Slightly buggy, but if played well, is VERY FUN.

Synergy is also an overpowered model, but it is more reserved and realistic overall. It bears similarities to TC++, but with a slightly different flavor.

Vidmaster Physics is ALSO an overpowered physics model, but not for you. No, your weapons are downgraded to pea-shooters. It's the ENEMIES that get the power, and if you think you've seen everything and you're truly the best, try playing this. Don't even think about Total Carnage.

More information is in the readme.

Notes for version 1.0.0:

Yep, believe it or not, here comes Bitsofglass Physics 2.0!!! Why changes so soon, you ask? Well, you see, I got a request asking for underwater shooting weapons. Your wish has now been granted!!! All weapons (including the flamethrower and fusion pistol) fire SAFELY underwater. All except for the spht' bolt rocket launcher that is. It is the fastest underwater propulsion method known to man. Just hold the key in which direction you want to go and fire away. Trust me, you'll be there in no time. The only downside to v2.0 is that the fusion pistol, even underwater, will still kill you if shot at close range!!! Have fun!!!!!!!!! :)

Notes for version 2.0:

The fusion pistol still may lock up your computer, so be careful. Otherwise the description pretty much sums it up.

A simple test of seeing how Divine Twilight's weapons (as they will be in Chapter 2) fares in a netplay environment. The player sprites and a few other things are currently unchanged from Chapter 1/original marathon sprites. This has only one map, a modified version of Infinity's Delusions of Grandeur (Delusions of Divinity)

The files in question that should be used in the event that there are issues with it automatically choosing the right things Scenario: dtmpprototype.sceA physics: sketchynetplayphys.phyA shapes: sketchyshapesch2pbtest.shpa sounds: sketchysounds HUD: Nech Tech Hud (Make sure to select the version that comes with this scenario as Ch1's is out of date)

Notes for version Divine Twilight Multiplayer Test:

Changed the scenario files to actually reflect the scenario itself so that people aren't setting it up wrong or trying to join with normal Infinity instead of the scenario

Are you tired of dying because you suck? Are you tired of dying because you were busy with your movement hand eating an ice cream cone? Are you tired of dying because the unskillful n00bs pwned you with h4xx0r weapons? Well fear no more! Professional Instagib is here to get rid of all of your complexity problems! Porfessional Instagib is not just any instagib mod, it has changes!!! From the creators of the MML music switch comes... Professional Instagib!

Notes for version 1.0:

PLEASE PLEASE PLEASE read the rules and setup guide! Just because you know how this works doesn't mean you know how this works! Version 1.0 will always be available when future versions come out.

These are plenty of physics I made using Hakvil 1.03 on my own time. These physics are made for Infinity, but if you try and use them on Durandal, it works too (I think). I took the time to make the mods more authentic, editing gun sounds as well.

Lazer Tag: Weapons mod.

Overpowered: Aliens are very strong/Weapons Mod.

Piercing explosives: Weapons mod.

Pretty Colors: Color mod (makes for a neat look?).

Quickdraw!: All weapons draw faster.

Super Punch: Fists have foward and backward recoil, 4000 damage w/ 400 random damage.

WTF?!?: Nuff said.

In the Player Physics folder: Feeling Doom?: Weapons have a side bob reminisant to how weapons in the Doom series moved.

Flying High: Typical flying physics (walking allows you to fly). Punches have foward and backward recoil to get you in flight.

Impervious: The player is invulnerable to any damage. Great for checking things on a newly built map?

Sonic Speed: You move twice as fast.

There are three? (I think) which will cause the game to crash...: - Overpowered - Piercing Explosives - WTF?!?

Enjoy!

These physics I made with a bit of a twist. I put in some more interesting things found in some games I was playing. Here are the changes:

Fist: Knock out punches (more damage)

Pistols: Pistoles (shotguns)

AR: Incendiary rounds w/ flamethrower attach

Shotguns: NADE FEST!!!!!

SMG: Incendiary rounds

Alien weap: Spht Kr bolts just like bitsoglass physics; 2nd trigg major

Whatever I didn't list has no change so rockets, fusion, flamer, I think thats it. Please comment, rate, critique. I really appreciate when you do.

Notes for version 1.0:

Tell me any bugs or anything I could improve. Thanks

WELCOME TO TC++ v1.4

As with all the previous versions of TC++, the main objective was to create something completely insane to add to the mayhem already associated with Marathon. All the weapon's have been changed, however, there are no flying BOBs, screaming Pfhor rockets, or anything like that. TC++ is actually a fairly simple modification to the Marathon weapons. All the weapons have been modified so that they fire more, fire faster, and overall, fill the level with bullets, energy blasts, and high explosives. However, this isn't one of those increase everything to max and have a completely Uber SPNKR that makes the player who gets it first God. TC++ is as balanced as I could get it. So, there are no ultimate weapons, the weapons are as close to their roots as I could keep them. The SPNKR is still the SPNKR, and the TOTZ is still the TOTZ. v1.4 is probably one of the more balanced versions of TC++. I've toned down some of the weapons, changed the rates of fire, and lowered the amount of damage done by some weapons.

So, if this is your first time playing TC++, enjoy it! If you've played the previous versions, this is an update to have.

WARNING: By saying 'Truly Amazing', we are sarcastic. Here is just some cool physics that make some things cool and somethings just down right irrelephant...

Notes for version v1.0000:

-Aliens are not friendly to any

-All guns do the same amount of damage -All projectiles travel at the same speed -All projectiles are guided

-Projectile Damage is 3/4 of your health

Okay so I've been messing with Anvil and come up with a few things

Fly by physics: Use with fly by wire LUA by Timothy.

Melee: You've been injected with roids, turning you into a lean green fighting machine. Your left hook is extra powerful, lunges, and is filled with roid rage. Also, the flamer has been reconfigured into a chainsaw.

NEFX loves you.

NEFX has been prolifically producing great Marathon/Aleph One inventions since 2017 (around 2.5 years after being founded) and uploading them to Simplici7y, in an increasing number of different upload pages that NEFX then frequently updates. This has occasionally lead to crowding of Simplici7y's front page with several different NEFX uploads, sometimes over a relatively short period. Understandably, some have objected to this as unfairly outcrowding and burying the wonderful contributions of our fellow travelers. We hear them. Therefore, to better serve the community as well as our Total Carnage Comrades, NEFX is now consolidating all additions and updates to its Marathon and Aleph One-related inventions on Simplici7y here on this one upload page, with a datemarked update timeline you can view below. Henceforth, all Marathon/Aleph One scenarios, campaigns, maps, mods, etc, and any updates to them, will be posted here. Of course, the webpage link connects to NEFX's Internet Archive homepage, where you can find all inventions by titled category. This includes:

NEFX Marathon Mods (i.e. physics files and Lua scripts for netplay)

NEFX Marathon Infinity Netmaps

NEFX Marathon Solomaps for others' scenarios, including the soundtracked 50-level pack for Aleph One: Wheels!
