Extinction: 100,000 Zombies killed. (Bronze)
Fairly easy if you are planning to achieve the developer medals. If not, go back through your favorite level and get some kills. I favor the Army Base.
Paint The Town Red: Fill the screen with the maximum amount of blood on any level. (Bronze)
Stand in a corner with chainsaw, and hold R1. When enemies come close, approach for a kill, than move back to your corner. I also suggest in a case of a large group of zombies, that you move in small circles.
Red Shirt: Kill the away team Zombie. (Bronze)
I remember hearing a little chime, shooting some zombies, and getting this trophy. No idea how I got it. However, I received it in The Graveyard on my first try, so no biggy here.
Hot To Trot: Last 30 seconds with 50+ zombies on fire. (Bronze)
I got this one in the graveyard. To start, get ballerinas or crazies on the field. Then light a few on fire and wait for the chain reaction. Since there is a spawn limit of 100 zombies, and zombies can only be alight so long before death, I suggest that you kill the first few you lit and light some of the new respawning ones.
Murder On The Dance Floor: 1000 Zombies sent dancing. (Bronze)
Grab the Groovitron Gun and start shooting. You will get this one if you go for developer medals.
Brain Surgery: 100 Brains sucked. (Bronze)
For this one, go to The Drive In level, and grab the brain gun. Suck as many brains as you can without dying. When you finally switch back to your pistol or other weapon, just light the zombies around brains on fire and TNT them. Lots of points and an eventual trophy.
Texas Style: 100 Chainsaw Combos. (Bronze)
You will get this one will going for Developer Medals. Ever time you get a kill with a chainsaw, it fills up the Combo Bar on the left hand side of the screen. Fill that up 100 times and Wa-lah.
Dynami-Te-He: 1000 Zombies blown up. (Bronze)
You should hopefully realize that Explosive kills give you 100*X points, X being number of Zombies on fire. This means that Explosives are easily the best way to get large amounts of points. If you are going for the Developer Medals, you should get this along the way.
Graduation: Complete Zombie Academy. (Bronze)
Complete the tutorial levels. I honestly thought they helped a good amount, and that you should definitely visit them first.
Tourist: All Arcade levels unlocked. (Bronze)
Play all Modes on The Woods and get at least a bronze medal. Then repeat for all The Graveyard levels. Ect ect ect. When you finally reach the Secret Lab, you do not have to get bronze there, because you just need to unlock the,.
Friend of Bruce: All levels unlocked. (Silver)
All levels unlocked. Do the same as Tourist, but also beat the first six challenges.
d6 Commends You: All Bronze medals. (Bronze)
Not to bad. Look at Friend of d6 for tricks.
d6 Respects You: All Silver medals. (Bronze)
A little bit tougher here. Look at Friend of d6 for more help.
d6 Admires You: All Gold medals. (Bronze)
Not only does d6 admire you, but I do to. This trophy is definitely one of the hardest. Look at Friend of d6 for more advice.
Friend of d6: All Developer medals (Gold)
First of all, this is easily the hardest trophy that comes with the game. Developer medals are generally 2-3 times higher than a gold medal. I have received one Developer Medal and one Gold Medal. That took me about 3 hours to get. I am not the best at the game, but I can give you a general idea on basic tips.
To start, kill lots of Normal zombies, and collect TNT. When you have 2 or 3, sprint through the zombies with your torch, and kill all of them with your gun of choice (NOT TNT.) Rinse and repeat till you have Remote TNT and atleast 1 range upgrade. Light all zombies on fire, and if you can use a brain gun into one area. Then run through the zombies once again and drop your explosive, then get out and press O. Each TNT should net you about 200-300 thousand points, if not MOAR!
