Greetings! I'm about to start a new Black Crusade game and would like to ask about memorable monsters for the first encounter. My group is a mix of players - one played D&D 4th E, one has never played RPGs before, and the third has clocked lots of World of Warcraft. I am the GM and ran Call of Cthulhu for nearly 10 years, played in Vampire the Masquerade RPG for about 6, and ran the aforementioned D&D game for about a year.
I am planning on running a few games based on the Tyrant's Cord scenario in the book that came with the GM screen. The party will consist of a Forsaken Chaos Space Marine, an Apostate, a Psyker and myself as a NPC Heretek. They will have recently escaped an Imperial prison ship and will have landed on a planet. I plan on having a combat encounter at every game session and will ambush them as they approach a walled city.
I'm looking for interesting monsters for this first combat - something memorable and challenging but I don't want to wipe out the team either.
I have several of the other core books - Dark Heresy, Rogue Trader, Deathwatch, the Radical's Handbook and Creatures Anathema, but I'm still looking for basic combat creatures. My campaigns tend toward the roleplaying side, so there will be plenty of plot-driven combat encounters - I'm looking for filler material I guess. The more interesting the better.
Suggestions welcome!
