Is there any way to rack up more points? I know you get a multiplier every 5 actions if you don't get hit, and I haven't noticed altering the difficulty making any different. The bonus modes also don't seem to add any points. I know you can be super sneaky/use a lot of human shields, etc to get a high multiplier but that doesn't really fit the character. I mean, I end up with most of the upgrades by the end of the game, but I'm wondering if there's an easy way to max it out. Thanks.
