Level 14 Rocket Race: I won! Doing what I just wrote. Took 28 kills from me-- my team got two. Stuck with my men as much as possible, stayed gold, and used Holy Grail as often as ammo allowed. Score was 30 to 24. I have been trying off and on for two days.
Level 14: Rocket Race (con't): Also, the bad guys have rocket launchers, which you will not have access to, so stay "gold" when you are on the attack. Your team is useful only for drawing fire (they'll get, maybe, 10 kills for you), so staying near them may be critical for victory.
Level 14, Rocket Race. I rarely do better than 16 kills and it appears that it will require 20. For what it is worth to others, I'm using: Resupply; armor plating, pick-up booster, and hair-trigger. I have success with the Hail Storm for the bad guys under me when on the jump pad; Hail Storm to clear a path and soften them up before I go anywhere, and Holy Grail for traveling down below. I reload while flying from a pad when possible and end the jump diving for the health beyond when I need to. Anyone have better ideas?
