How are they. Well they're fun. But they're different.
The versus maps are easier to address so lets start there.
After playing through Dead Air and Death Toll on versus it makes you question a few things.
0. Was there a huge surge of people to decided to start playing Left 4 Dead again now that there is new content?
1. Did the player base recently all become newbies somehow?
2. Are these maps simply just too new for people to understand how to survive them?
3. Is this why these maps were not available for versus play up until now?
I say this because wiping is fast and frequent in these new maps. Prior to the the patch you could randomly join some guys in versus and be reasonably sure that you would do alright assuming the other team is stacked full of friends who have pre-planned everything. Post-patch
The three above points cover my main thoughts as to why there is so much wiping in versus.
Lets get rid of #3 and #2 right away. Go play the old versus maps and you'll see early wiping occurring as well. Although #2 may explain why it is much more so in the new stuff.
This means everyone either sucks now, or people came back after not playing. You can figure that one out.
I will say this. The versus maps that just came out are far more difficult than the other two. There are many more options for flexible and diverse attacks and further the fact that many are unaware of where attacks are likely to come from means that it is harder to defend against them.
Simply put, we've got a compounding situation. The new maps brought back people who had left, but the new maps also confused many.
The maps themselves? They're good. But like a said they feel pretty lop-sided in favor of the Infected side.
So the other half of the update is a new mode that seals off sections of the maps and tasks you to simply not die. How is it. It is either too easy, or too hard. The one map made specifically for this task "Last Stand" is exceptionally hard. But it is in a good way. You can't simply adopt one strategy for it and find success with it. I've tried numerous strategies that all work fairly well for a time, but ultimately crash and burn.
That is the problem with the other survival maps, culled from prior content, they are making the best out of what they have. Some are easy, and involve just standing near the ammo and dropping tanks with 3 auto shotties ASAP, while the M16 guy picks off smokers and other specials from a distance.
Overall I really enjoy survival, but it makes me want to play with friends more so than any other mode. You really have to be comfortable with these people to tell them your opinions on where you think you should shoot zombies from, or rather what the general plan for your survival will be.
So the survival pack? It sure was good for me. And really free content... kinda hard to bitch about it.
Strange side note. I've seen more girls in Left 4 Dead matches since the patch, which is worth noting because girls either hide their gender, from fear that everyone else in the game will begin to hit on them. Or they wear it on their sleeve and torment all the guys in the game to make them feel shit. Please note I am not suggesting that more girls playing Left 4 Dead is the reason that there are so many wipes. In fact the girls were better than most other players, myself included.
Well yea. Zombies and Girls and such. CRAZY!
