Welcome Eternus
The Imperial Fists first introduced the Titanhammer Terminators with the following stat line which should be the same:
Quote:
Terminator Assault INF 15cm AR-4+ CC-2+ FF-n/a
Thunderhammer / Storm Shield (contact) , (Assault Weapons), EA (+1), MW Reinforced Armour, Teleport, Thick Rear Armour, Invulnerable Save
Essentially they lose FF and shooting attacks, and gain the extra CC, and an INV Save.
They are the same price as standard Terminators as it is yet to be shown that their CC boost is not proportional to what they lose in defence and general strategic use (as they are so specialised). Effectively, they are great when they get to where they need to be (teleport) yet after that they are easily dealt with (broken through FF combat and then followed up with killing them off through blast markers on a broken unit).
I hope this helps.
Cheers......
