Heck, some levels come one after the other with no break to restock at headquarters. That's got me stuck near what I suppose is the end. I wish I'd known I might be protecting the mayor's mansion from wave after wave of killer robots. Instead, I packed for the mission immediately before it, an urban hostage rescue. The only ammo to be had is from dead cops, since robots don't drop any, and none of them actually packed the heavy weapons I need. I can either reload and lose a couple of hours of play, or stop playing. Guess which I chose?​
