Pros:

The Classic Amazing version, not the Spidey movies version.

Cons:

there may be a texture issue on the hands, but I can't really tell

Conclusion:

By far one of the better mods/ports I have collected.

I'm not a big fan of Marvel, but it covers up Ellis, so I like it. Too bad there is no custom voice over to remove that annoying southern accent... no offense to anyone whom reads this, just my opinion.

Pros:

This is what Venom should look like.
Made the Tank a bit scarier.

Cons:

A bit out of place, but that doesn't take away from it.

Conclusion:

I'm not a huge Marvel fan, but this mod is a must have for anyone looking for a different skin for the Tank.
This is the Venom we all know and love, not that Spiderman3 dribble.

Eddy Brock never looked so good in a game.

Great job!

Pros:

Original
Colorful
Challenging
New weapon?

Cons:

It takes some getting used to
there is a section of the map that kills the player instantly if jumped down upon. (not really an issue, just easily forgetable)

Conclusion:

I love this map. 

There are so few things more satisfying than Blood splattered Neon.

If you haven't downloaded this map, WHAT'S WRONG WITH YOU???

Pros:

He's a zombie killing machine.

Cons:

Model has stretching issues, texture issues

Conclusion:

"Dead or alive, you are coming with me."

This mod is awesome! It is definitely a treat watching RoboCop mow down hordes of the undead.

However, this mod has a few issues that bring it's score down.
The textures feel very plain and almost placeholder. There is some abnormal stretching upon the elbows  and other joints that take away from the mod.
Still it is a good mod.

Pair this mod with the ED-209 and Terminator Common Infected Mods, to create a twisted retelling of Robocop vs The Terminator.

Great job

Pros:

It's ED-209.
Must download for anyone who likes RoboCop

Cons:

Only mapped to the lower half of the Tank.
Textures seem a bit muted.

Conclusion:

"Put down your weapons, you have 20 seconds to comply." "SHOOT THE DAMN TANK"

This little mod is a nicely crafted replica of Ed-209. Slight Texture issues aside (I feel there could be more detail), it fits in nicely with the l4d2 universe. 

This mod is weighted mostly to the legs and lower torso of the Tank. Which makes sense since it is mostly just legs and a torso, but there is a feeling of space between the tank and the player, that just feels out of place, with this mod being without arms.
But all in all this does not take away from the Mod, nor the experience of the game.

Pair this mod with the RoboCop and Terminator Common Infected Mods, to create a twisted retelling of Robocop vs The Terminator.

Great job

Pros:

It's awesome!
It brings you back to a simpler time.
It gets covered in blood!
HUD images, name chage

Cons:

slight issues with the model

feels out of place when not in Pallet town.

Conclusion:

He wanted to be the very best. Now he is...
The perfect accent to the Pallet Town Map.

As this is the Trophy model from SSBB, there are some apparent issues with the model. The seams along the face, for the eyes and mouth, along the hands and cross seemingly random areas of the model show Nintendo/Hal Laboritories weaknesses with character modeling/the Wii's low poly limits.

A nice import, I feel it would work better on Ellis however.

Pros:

Hands down, the funniest Mod I have downloaded.

It's the T-800 and the T-600 what more could you ask for?

Models are perfect!

Blood? I see your robot is leaking coolant...

A simulation of ravenous machines, who have also been struck by the economic hardships and can't afford weapons themselves.

Cons:

The surprise of which downed zombie will stand up is ruined with this mod.

Can cause the game to lag a bit if too many are on screen. (but this is testament to the detail in the models)

Conclusion:

Such a fun mod! 
The Chuckles I get from watching these machines tear across the map, attempting to ravage me and the other survivors. Only to be taken out with a well placed bullet. 
If John Connor knew it was that easy, the war would be over.
Although not in the same style, pairing this up with the Ed 209 and RoboCop mods makes for a great re-imagining of Robocop vs the Terminator.

As the Cons say, there is no longer any surprise as to which Infected will stand up when you enter it's proximity. One look at the piles of bodies will show you Zombies and Machines lying upon the ground. Where as without this mod, every corpse could be a potential enemy. 

If there is a way to fix this issue, I highly suggest an attempt at it by the Modder. Not that this Mod isn't hands down one of the best I have downloaded either way, but it would be a nice touch to hide the rest of the undead with machines.
