it's annoying how when you accidentally press the wrong one you die just make it do nothing, i know this is so theres no button mashing but it's really annoying when you have barely a second to react to things
(best tactic here) climb onto a rock wait a bit for about hmmm 100 zombies to come take out your rocket launcher and POW pick up the upgrades and stuff and do it all over again
Im sorry ;'( I should be working on something new soon though! Cross your fingers ;)
