- Abstract
-
-
- Marathon isn't much geared toward defending anything. The weapons are
- built for attack and you usually have to go to the monsters. And the
- puzzles can get a little monotonous. To inject both a little more
- strategy and a little more action into the game, I designed a new physics
- model. The action's faster, the monster's are smarter and the weapons
- are, well, quite different (think landmines).
-
-
- Not just a semiconducting sports drink
-
-
- You're liable only to read this file after trying to use the model
- and getting clobbered. (I'll assume you all play at total carnage which
- is the most fun for this model). First, let me reassure you that all the
- levels can be completed, but some will make you remember how hard
- Marathon was when you first started playing.
- If you want a real surprise, stop reading after this paragraph and
- go right to playing. Just run like hell for a safe place at the start of
- every level and try experimenting with the second triggers of all the
- weapons. If you have trouble with any particular level, consult the
- spoilers below.
- On a personal note, don't tell my dissertation supervisor and don't
- expect much from me in the future. I designed this model with someone
- else's game disks. I've deleted the game from my hard drive and returned
- the disks so he can play. Since I haven't used this physics model in a
- while and I experimented with a variety of them, I may mix up a few of
- the facts below.
- On to the basics.
-
-
- Changes to the monsters
-
-
- Most monsters are now omniscient and can see you from a distance.
- They'll come at you pretty quickly from all directions. You may notice
- your game play slow down when you first start a level because all the bad
- guys are moving around. The best advice when starting a level is to run
- for a safe corner (usually a recharge station) where you can knock them
- off. Oh. And most of them fly so expect to see things clinging to the
- ceiling and shooting at you in the dark.
- Specifics.
- I don't know what I did to the compilers, but they sometimes get
- stuck in walls and/or travel through them. I have no idea what's going
- on. So far they are the only ones. (Bob's just fly up and down
- oblivious of the laws of space and time (even when they're corpses).
- Hulks and juggernauts are now small enough to travel the
- passageways. "Try Again" gets very interesting. You might want to
- consider adding juggernauts to each level, they're so fun.
- I can't remember exactly what I did to the enforcers, but I think
- they only carry alien ammo now. You'll have to go into one of the secret
- rooms to pick up a weapon. (I kept dying when I ran over an enforcer's
- body and the flame thrower changed into an alien weapon).
- Oh, I never could get the Bob's to attack, but I did manage to
- stop the defense drones from being as helpful as they once were. They
- won't fire on anything now unless first fired on (including you). They
- shoot plasma overload bursts, so don't get them angry.
-
-
- Changes to the weapons
-
-
- Fist. I've changed the fist speed so you can punch the fighters
- before they smack you. The fist can also be used to propel you upwards.
- [See physics changes below].
- Pistol. Altered the ammo in the clip and changed it to emit an
- alien shot (can't remember which). Not a weapon often used, though I
- think it can now trip switches.
- Machine gun. Emits plasma shots. The most effective weapon, next
- to the flame thrower. Can't remember what I did to the grenades.
- Fusion Pistol. Can't remember exactly but I think it emits a
- compiler bolt in normal operations and a special shot that looks like a
- hovering staff bolt on overload. The 'mine' is actually an unused shot
- whose velocity has been set to zero. It doesn't do much damage but the
- little fellows will just run smack into them and bean themselves. You,
- on the other hand, can walk right through them. I've never tried this
- model on a networked game, so I don't know if other players can set off
- these 'mines.' Let me know. [Disclaimer: Not responsible for any
- dehydration in your computer's EEPROM electrolyte replenisher during
- network play.] Mines are great for leaving around shield generators to
- keep the baddies from getting to you while you take a breath. Try not to
- leave more than 32 shots/mines active at any given time. Although the
- game won't crash, very strange things will occur...
- Flame thrower. This one is a bit of a misnomer because it no longer
- shoots flames. The primary trigger shoots plasma overload bursts (in an
- interesting pattern) which will quickly kill anything nearby (even a
- Juggernaut, so don't stand close). It's not a great distance weapon, but
- it'll serve in a pinch. The secondary trigger lays a fusion land mine.
- It looks like a plasma bolt on overload that hovers in the air. Don't
- stand nearby when it goes off. It'll kill a fighter in one blow and will
- probably hurt an 'invincible' player. This is the main weapon of the
- model. When aliens start chasing you, run and leave a little trail of
- mines, or use them defensively to shore up your hideout. Let the
- monsters come to you through a minefield.
- Missile launcher. The secondary trigger now shoots cruise
- missiles. Like the other mines, they hover right where you shoot them.
- This missile is a little more powerful than normal ones and has a large
- blast radius. Only if you have full 3x shields will you survive (hiding
- behind doors and around corners will do). Use these for the juggernauts
- chasing you. (Perhaps a better name for this model would be 'Hey! You
- sank my Pfhor!")
- Alien weapon. Couldn't really think of anything to improve this
- weapon. I mean, what, you want enforcers shooting plasma overload shots
- at you?
-
-
- Actual physics changes
-
-
- Keep the [CAPS-LOCK] key down to run everywhere. The walking
- physics has been changed. You'll now move incredibly fast when you
- 'walk.' Also, the gravity's been turned off. If you lean down, run
- forward and punch, you can fly and climb up walls. This takes care of
- solving most of the game's puzzles.
-
-
- Level Spoilers
-
-
- Here are some hints for the hardest levels.
- Arrival. Run quickly to the right into the large room, punch and
- open the secret panel in the top corner. After that, you can shoot
- everything one at a time.
- Bigger Guns Nearby. You have to kill all the fighters right away.
- Kill the two or three that you find immediately, pick up the boxes of
- ammo closest to you, then situate yourself so that they have to come at
- you one at a time through a narrow passage, then punch them one at a
- time. If any get around the one in front, you're finished.
- Couch Fishing. Go down to the end of the hall adjacent to the room
- with the compiler in it (lower right on map). Turn around and shoot
- everything. The trick of getting all the Pfhor to fall into the chasm
- under the giant door will no longer work, so you have to clear out the
- big rooms by force.
- The Rose. Don't run anywhere right away. You'll have to kill the
- two fighters that are now standing just outside the windows. And their
- friends (as well as defense drones) will come up the lift.
- Smells like Napalm. Run for the shield generator, turn around and
- shoot. Most of them will come right at you. Don't forget to pick up the
- flame thrower (it's easy when you 'walk').
- Cool Fusion. Get to the 2x generator ASAP. Pfhor will drop out of
- the ceiling soon.
- G4 Sunbathing. Get to the shield generator ASAP and lay mines with
- the fusion pistol. Run around the big open rooms for ammo at your own risk.
- Blaspheme Quarantine. As usual, use the first lift to trap and
- shoot everything (put a bunch of fusion mines in its narrow hallway).
- Bob-B-Q. There's a small circular room with one fighter on the
- right side of the map (below it is the entrance for the snaking passage
- to a shield generator). The only way I've survived is to run immediately
- for this circular room using the flame thrower to lay mines. Be
- careful. Some of the Bobs are under the floor and can pop up to set off
- the mines, so don't start right away. Line mines up and down the hallway
- outside the smaller O shaped room and then hide in that room to avoid
- enemy fire and go out to periodically lay new mines. This takes a long
- time. Then go for the shield generator (laying mines behind you).
- You'll have to clear out some ledges. It helps to have 2x shields from
- the previous level.
- Fire! Fire! etc... Run for the shield generator in the room next
- to you. Lay mines in the entrance way and wait. Some troopers will
- eventually get to you. Don't go out after them.
- Habe Quiddam. One of the most frustrating. Run for the shield
- generator right away, laying mines behind you. There's a long corridor
- above the generator. Hide there and lay mines both in front and back.
- Wait. Keep luring the Pfhor back there.
- Pfhor Your Eyes Only. Use cruise missiles and fusion mines to stop
- the onslaught (hide from the blast around the corner). Go straight down
- the corridor to get to the room with the shield generator. Don't waste
- time trying to save your game (you can get trapped in that room).
- Remember to shoot everything off the ledge and use mines and strategic
- retreats to kill monsters that are far off without getting hurt.
- Remember to grab an alien weapon from the secret room if you want to use
- it (hell, collect the set).
- Unpfhorgiven. Run out as far as you can, then retreat while laying
- mines. Repeat at 350 degrees until done.
- Beware of Low-Flying Defense Drones... Beware of all drones. Don't
- leave too many mines laying about or one will run into it. When you
- first start, don't go anywhere. Blast the two enforcers that at you,
- then turn and shoot the floating trooper. Try to get one of the drones
- between you and an alien to it will wake up when it's hit. Jump down
- into the pit after you're sure the other trooper is dead. Actually,
- you'll need to go down the lift first, leave a cruise missile outside the
- door, open it, run back to the lift and then shoot to draw all the aliens
- out. Otherwise, they can come up the lift after you (remember to always
- protect your flank in this version). The same missile trick can be used
- to clear out other rooms. Remember to pick up the invincibility and
- immediately 'walk' back to the teleporter to leave the level.
- Eupfhoria... Run like hell for the shield generator using the
- flamethrower to clear a path. Don't lay mines because they will hurt you
- through the invincibility. You can do it methodically by going from room
- to room but it's a lot trickier. Remember to lay mines in the hallways
- leading to the generator. If you don't, wasps will get through.
- Pfhoraphobia. Tough. Lay mines at the secret entrance to get the
- fighters that are running at you behind the door, then quickly go into
- the room with the compilers and kill all three (leave some mines behind
- you). After that, no game is ever the same but here are some things you
- can do. Crisscross the giant platform with mines so that the compiler
- that tries to come up on it will get clobbered. Lay mines all along the
- double doors, then encourage the aliens to follow you (missile mines work
- too, but make sure you don't waste them on just one monster). I'll let
- you discover the rest.
- Ain't Got Time Pfhor This... It helps to have the invisibility and
- infravision before getting here. Use the flame thrower (it won't have to
- reload as quickly as the machine gun) to kill all the wasps, then
- recharge. Wait a long time, then go into the main room. Open the door,
- take a look but don't go in and run back. With any luck the troopers
- have killed each other. If not, they can easily kill you right here
- (esp. if the door closes behind you) and there isn't much time to lay mines.
- Try Again. If you want to save your game then do it right away,
- then fly across the room to the far right door, begin laying mines and
- running everywhere. Don't ever stop. The juggernauts can corner you in
- the halls quite easily. The best level in my opinion.
-
-
- Fun Variations
-
-
- Change the fusion pistol to shoot compiler bolts (they knock the bad
- guys back farther than anything else and disorient them). Change the
- fusion overload to fire fast moving grenades that aren't affected by
- gravity and have a large damage radius (a good distance weapon). Pump up
- the gravity on the wasps and watch the little *($%#$'s scuttle
- helplessly along the floor.

- If you like the physics model, then check out my Persistence of
- Phosphor Screen Saver. A demo has been uploaded to Sumex and you can
- request a copy by emailing IMP@EDEN.COM. It's the only screen saver to
- support everything from 32bit color animation to 1 bit pattern
- animation.

- Notes
-
- * The name for this model was suggested by one of the analysts on the
- financial news channel CNBC. He was making a joke about the hi tech
- companies that made products he couldn't understand. Sorry, but 'field
- programmable Gatorade' isn't a real product although I will take orders
- for it (expect a high book-to-bill ratio).
