I just played my first solo game with Blue, Yellow and Green (Chosen randomly) and I had some questions come up.
1) If I roll a 3-skull while attacking do I kill 3 GS or just 1?
2) If I use team A's MOVE + ACTIVATE card to swap with B, can I change the facing on B as well since he also moved?
3) I had a Swarm of like 7 on Lorenzo? from Blue and I used Counterstrike that turn, would that keep him alive as long as he kept rolling skulls? or is 7 just an instakill?
4) If your Space Marine is facing the wrong direction, he can still defend right? Just not use a support token to reroll.
If the answer to 1 is 1, then how on earth do you keep up with the spawning? If you had all three teams attack AND they were all facing the appropriate direction AND they all rolled skulls, you could kill 6 GS per turn. But the chances of all 3 of those conditions happening at once are slim and none. Even in the solo mode of spawns of 2/1 I had swarms of 5-7 by the 4th or 5th turn.
1) You kill just a single genestealer. There are special abilities that may change that, but in general most marines kill 0 or 1 genestealer, depending on whether or not they get a skull.
2) No, only the team whose Move + Activate card is being used gets to change facing.
3) You still roll the die no matter how many genestealers are in the swarm, so if he rolled a lot of skulls in a row he could whittle them down or even wipe them out. Or he could get unlucky and die by rolling a 0, 4, or 5.
4) Correct. If you're flanked by the attacking genestealers, you can't spend support tokens, but you still make a normal defense roll.
Un-numbered question) Keeping up with the spawning can indeed be difficult, and is the primary source of dramatic tension in the game. Note however that there are a number of teams that have special attack abilities that will let you get ahead of the odds a bit. In just the Blue, Yellow, and Green you used in that game, there are 4 abilities for doing so. Blue has his defensive counter-strike and the ability to intimidate 'stealers back into the blip piles. Yellow has a special attack that kills 3 genestealers automatically (but is sometimes sacrificial). Green can sometimes get lucky and kill 3 Genestealers on one roll.
In addition, support tokens can be used to reroll attacks, and are definitely worth using to keep swarms from getting to 5 or more in size.
Also, just how difficult the game is depends a lot on what Event cards you draw in what order, so it's possible you may have experienced a harder-than-average run on the event deck. Shuffle well and try again.
