Yes. Al you need to do is catch either one of the pokemon mentioned, for example Archen, then get a friend to trade from black -> black or white -> black with the other pokemon (in this case Tirtouga) to you.
Archen is way better.
In Nacrene City, you can find Archen and Tirtouga in the Dreamyard, a location accessible after you obtain the first gym badge. Specifically, Archen can be found by using a hidden item or encountering it in the area, while Tirtouga is available as a reward for players who choose to revive fossils at the appropriate location in the game.
there is a backpacker in relic castle who will give you either a plume fossil (which is revived into an archen) or a cover fossil (which is revived into a tirtouga)
When breeding, the egg will always be the same species as the mother (the only way to get around this is by using ditto). If you have a male archen (which is likely, because archen is usually male), you're out of luck and will just have to wait until you can acquire a ditto.
To get Tirtouga, you must travel to the Relic Castle, to the west of the construction yard between Castelia and Nimbasa. In the Relic Castle you will find a Hiker who will give you a fossil of your choice. You can choose the Cover Fossil which will turn into Tirtouga, or the Plume fossil which will turn into Archen.
trade with someone
Zorua,reshiram,tirtouga,archen
Cover Fossil is Tirtouga. Plume Fossil is Archen.
Tirtouga from the Cover fossil, and Archen from the Plume fossil.
Archen is way better.
There is a lady with a backpack on she gives you either a plume fossil(Archen) or a cover fossil(tirtouga)
tirtouga evolves into carracosta at level 37. if you wanted to know this too, archen evolves into archeops at the same level as tirtouga to carracosta
You need to go to relic castle and the backpacker will give you a Tirtouga or Archen fossil.
No.
You can only get one. Unless you have an action replay and pokemon modifier for it. You can also just trade one of them from pokemon Black version. I hope you like my answer Rayquaza394
