The Tranzit campaign is for those who don’t want to stay in one spot and shoot nonstop. With Tranzit, you can travel to and from four locations; A farm, a store, a gas station, and a power plant. In between you ride around on a modified anti-zombie city bus with a big plow on the front for taking zombies out at the kneecaps. As you travel between locations, there are secrets aplenty to be found and challenges to be completed that can open new areas. The only issue is that you have no idea what the end game is. Nothing is apparent except that the world is full of zombies and you have to survive it. The final destination is not apparent nor is there a story of any kind.
You can find things in the world to build new equipment, but finding them is a pain. They don’t glow; they’re not distinct from the surrounding world. You have to be right up on top of them to find them, and then have to be looking directly at them to pick them up. It’s a game of Where’s Waldo with zombies trying to tear you apart and teammates rushing around shooting while you try to focus on finding this stuff. I’m sure it gets easier each time you play it, but I can’t see myself wanting to do this over and over.
Honestly, if you have never played any of COD’s zombie modes, then you will probably be completely lost. The steps to unlocking new areas can, at times, be nothing less than cryptic, and piecing the storyline together and getting the whole thing to make sense is really more trouble than it’s worth.
