Server-Side Fixes to some Annoying Versus Problems

PLEASE NOTE: The latest Valve update has rendered most of these plugins null except for, possibly, the Unscrambler. Even then, it’s possible that the plugins are incompatible with the new version of the game, so I recommend you remove them and/or check Allied Forums for updated versions or confirmation that they’re fine with this version.

Take this situation:

You’re on No Mercy, the 3rd map, the Sewers, playing as Infected. You’ve done a bit of damage with a fast attack soon out of spawn, countering the initial Survivor rush to the left. Licking your chops and grinning with glee, you get ready to time your spawns around the lift, the infamous crescendo in which the Infected have a wonderful chance to do some incredible damage, if not win outright.
But what is this? They do not even look at the lift. Instead the entire team runs to that door to melee it 67 times and skip the crescendo entirely. An opportunity is lost, an exploit found, and the game loses value as a result.

Some would say that it’s not really an exploit, as both teams have the chance to do it, but I beg to differ. It renders the lift crescendo completely useless as, with a bit of knowledge and melee spam, the Survivors make it instantly easier on themselves and devalue their victory accordingly (as their use of it, like the use of crescendo closets, all but forces the other team to do it). But that’s an argument for another post.

But there is a light to this, a beacon casting back the soulless exploits and lack of fun in the shadowlands. The champions at http://www.alliedmods.net/, namely Fyren, KawMAN and bman87, with Ydiss as their public relations officer on the Steam Forums, have worked at and succeeded at making some temporary fixes for four of the more annoying exploits and griefing attempts.

All of these fixes are server-side, so they require the Server Owners themselves to install and implement these modifications into their servers. This is to just get the knowledge out there. I strongly urge all server owners to implement these plugins to give clients a fairer and more vanilla game.

The Fixes

TAKE NOTE: The plugins require MetaMod:Source and SourceMod 1.2 to be installed on the server. I’m going to assume owners have the proper knowledge to install both SourceMod/MetaMod and the accompanying plugins. If you’re new to server ownership and don’t know, or just have some questions, just reply in comments and I’ll see what I can do to help you.

No Mercy Map 3 Shutter doors Exploit Blocker - This plugin takes the shutter door on the Sewer level and gives it 100,000 health, thereby forcing exploiting players to either bypass it (thereby taking the intended crescendo route) or sit there and melee it for a couple of hours. Tanks can still bypass the door in both directions, so Infected play is not changed.

Kill Blocker - This blocks the “kill” and “explode” command from clients, preventing griefers from joining a game and suiciding at the worst moment.

Unscrambler - This plugin takes the team layout from the end of the previous map and forces it on teams in the first 30 seconds (time is changeable) of the next map, circumventing the random swapping of teams on a map change, and stopping people who load maps quickly from swapping, taking a slow-loader’s place on a team before they can join.

Infected Spectator Exploit Fix - This kills a player if they join the Spectators straight from the Infected, preventing the cloning Infected exploit. It will not kill players who have to play Tank, so don’t worry about it having off side-effects.

That’s all the exploit fixes known so far. I’ll update this if and when more fixes are available. These are only temporary fixes, until Valve decide to jump on these issues themselves. I have a server at 64.156.14.109:27015 with these plugins implemented, if anyone was interested.

Once again, many thanks to the folks at Allied Modders for putting the time into this. This thread at SteamPowered informed me of it all. Thanks to Ydiss for spreading the word.

    Man, I hated that exploit. There are many exploits similar to this that need to be fixed. Anyone seen someone use the ramp during the No Mercy finale? Only a tank can beat that.

  2.  

    Glad to see someone is trying to fix the exploits.

  3.  

    This is excellent news and I’ve already seen the likes of it used on some servers already. A couple of other things I’d like to see fixed for versus is the removal of all “Hero Closets” from versus as without survivor respawns they have no purpose and also a fix to the Helipad ramp in the No Mercy finale to stop the survivors from hiding under it with auto shotguns rendering all boss infect including the tank utterly useless until the chopper arrives. With any luck the up coming DLC for L4D will fix most of these bugs and exploits as well as adding Death Toll and Dead Air for versus.

  4.  

    I never did understand exactly why they left the closets in on versus mode considering according to valve versus mode requires, “a complete retooling of the maps” from those that have accidently gotten onto Dead Air in versus mode can guess this (buildings lacking rooves etc.) so why have the closets left in at all if your going to redo the entire map?

    Laziness perhaps (well lets face it they had to add a crapload of stuff to make the maps work for versus so I imagine they just got tired by the end of it) or just not realising people will not play the game how they envisoned it themselves.

    The NM3 door is a key to this, the dev commentary on NM makes a real big fuss about the ‘crescendo points’ such as the lift area but failed to realise the players could simply smash down the door and ignore their wonderfully crafted moment of tension.

    What always annoys me though with the NM3 door is when the first team does it the right way with the lift and the second team goes and smashes down the door…if the first team did it the right way so should you damn it…

  5.  

    I’m not aware of that exploit. What’s it all about?

  6.  

    Getting under the pipes in the 2nd level of No Mercy (in the generator room) is pretty cheap too. Three people can easily sit there and melee, and infected can do nothing against it.

    There’s also the griefing that can be done with ladders + health pack, that one is pretty cool. Or if you are on top of the building in the final act of No Mercy, getting the gun to launch you off the map is pretty fun too. What’s the actually purpose of the chain gun launch?

    Hopefully valve takes care of these things :)

  7.  

    like Bassem.B., i’m not aware of the exploit mentioned in the post

    but what i DO want to be fixed is the cloning spawn for the infected. me and my team got messed up last time on NM finale by 6 smokers, 4 boomers, and God-knows-how-many hunters.

    oh, and pop in 2 tanks too.

  8.  

    The first time I witnessed the exploit I was playing as Infected. Happily, we just royally screwed them over with everything we had while they were meleeing the door. When the door finally came down, a boomer was on the other side. They might have been better off taking the lift…

  9.  

    Aww. I’m going to miss BOTH jumping off the roof and booming them while they’re meleeing AND waiting for the door to come down to boom them. :) See? Easy fixes. Also, I woulda waited on the left side of the door, because some will shoot right through it for no good reason. No Mercy is cool yo.

    Also wondering if the update will include a fix for the double melee glitch (or, if you’re a programmer guy, scripting for super melee).

    AS LONG AS IT HAPPENS AFTER THE TF2 UPDATE!!!!

    @Kristoffer Truitt

    The launcher thing doesn’t have a purpose, it’s a glitch. The gun has physics, that can’t move. V Physics thinks that the gun has so many melee knockbacks worth of movement, and when you jump off it weird stuff happens and you get that amount of movement injected into you.

  11.  

    @Noob

    There’s a really easy server-side fix for that exploit too. A number of servers have implimented it.

    As for ‘Hero closets’ I think it’s really just more an oversight on both cases. Really, nobody complains about closets in general, just that closet that’s 5 feet away from the Crescendo, rendering it useless. The Ramp, also, renders the Special Infected moot. Even the tank is somewhat suspect in value, as it’s common for the Survivors to load up on Auto Shotguns, and the Tank doesn’t last long forced to endure all four of them.

    In both cases, it isn’t really that it’s not a viable strategy–it’s the most effective ways for the Survivors to survive, thus a viable strategy, but as far as gameplay–it isn’t fun in the slightest. All the Survivors do is spam melee until everything falls over–Special Infected ‘wait it out’, as all Pounces/Smokers are rendered useless (and the Boomer, try all he might, can only summon infected that will die in the same way as the rest). For that reason alone, they need to be addressed, regardless of how clever some people ‘feel’ for having discovered that ridiculous bottleneck = Win.

    Why does the door have health at all? It should be invincible, shouldn’t it? I haven’t played L4D, though, so I don’t really know if there’s something that requires it be breakable.

  13.  

    Sarda: The doors were made breakable, because all doors in the game are breakable, if infected are on the other side pounding to get through to you they will eventually get through. Although the devs didn’t take into account the ability for survivors to completely smash through that door, as with most doors survivors are only able to smash it to 90% heath with bullets or melee, while infected are allowed to smash it to 100% dead.

  14.  

    Hmm. The jesus room need to be removed, that’s for sure.

    Why can’t the doors just be made to not take damage from survivors at all if they’re not meant to get through?

  15.  

    I can’t wait for Valve to patch the movable objects. The blocked elevator, the sewer with a dumpster over it, etc. It annoys me beyond all else, and I have to wonder why they do it? They can’t really hurt us, and we’re stuck in very good holding spots. We just end up waiting until they get bored and move it. I hate exploits.

  16.  

    @Led

    They already patched that for PC.

  17.  

    I split a server with my friend, it’s our first server and kinda flying by the seat of our pants (I just found out how to link it to a steamgroup). I did look up MetaMod:Source and SourceMod but I can’t wrap my head around it. Where would I download it to, would I change the scripts in the the server menu? I would love to add mods like this and custom maps and things of that nature but there is no begginers guide and if I screw up I have to start from scratch again. If it’s not a problem I would appreciate the help with how to set up the mods. Thanks.

  18.  

    Ah, thanks Dr. Target. Good to know that we 360 players will get a patch eventually.

  19.  

    @led

    Not necessarily. Look at TF2

  20.  

    [...] the glitches in Left 4 Dead just seem to keep up coming… We’ve seen such things as knocking down metal doors with your bare hands, but how about making your teammates teleport? Through an elevator floor and to their untimely [...]

    the blocked elevator glitch in no mercy cost my team the match, i thought it was an admin command at first=(
