I liked that after getting missions with mostly vehicles you suddenly placed missions with lots of infantry swarming the player.
That suprised me and so I had to switch weapons back to the Uzi which then allowed me to get rid off the infantry soldiers faster.
Btw. is there some kind of condition for one's score in the 1-life-challenge to be added into the ranking list?
I have a higscore of 966 since yesterday but my score is not even added into the list for my own scores at all.
