Welcome to the part 2 of Ultimate Doom on Nightmare difficulty with assist included. This time we are doing Episode 2. And unlike the first part, this time Caleb the undead gunfighter has his own sets of weapons rather than using Doomguy's sets of weapons. His inventory includes:
1) Thompson SMG (Tommy Gun)
2) Napalm Launcher
3) Tear-Gas grenades
4) Tesla Cannon
5) Blood Scepter Staff
Note: The zombies are replaced with hands abducted possessed marines from Bloom which are deadlier than their original counterparts, especially on Nightmare.
So that's about it :)
