- The clueless homocidal neanderthal - shoots the first thing that moves, ignores all sprites, keys and messages, thinks it's just deathmatch.
The marathon runner - grabs keys but runs away from teammates who also have keys when the "RUN HERE" sprite is displayed... ignores all messages.
The bloodthirsty snob - is too proud to pick up dropped keys even when right next to them... prefers to let the enemy pick them up and try to kill them later.
The obsessive-compulsive attacker - picks one person to attack and ignores everything else, even when he could easily collect keys or prevent the enemy from scoring.
The semi-oblivious camper - somehow manages to get a key then camps somewhere difficult to reach quickly (usually as high as possible)... will ignore teammate key carriers and "RUN HERE" signs even if he could just jump right on them and score.
