Why not make the perks and upgrades scattered around the track so you would have to find them, and then pay with your points to upgrade? (This can be done mid-wave) Personally, I think that the zombies should have no limit, so it would be completely unpredictable on what their spawn pattern would be. For example, the zombies could spawn in a pack to take you out with brute force, or they could spread out and then attack by stealth or ranged attacks. I think it could work either way.
