concurred, this kinda game is a waste of time until you get really good at playing, which of course you will if you keep practicing hard against those odds but i should imagine 5yrs will start showing draws...
okay if you are gonna play like this first thing:
guess range weapons, kill em however you can - nothing is more important
once these are done with you need to knock out the faster units, immobilise the enemy
finally finish up what you can taking care not to expose yourself
next thing:
stealing is bad and wrong, give the store the thiefs name etc. it's the right thing to do.
finally:
don't bother - play against yourself rather than this idiot.
