i found some problems
heres a problem i found: i decided to upgrade only the shotgun mode because its my favorite. that strategy was doing great it even became easy i could kill anything very quickly with my unupgarded guy who had an upgraded shotgun. only problem: as i continued to upgrade my shotgun it transformed into a laser canon - which sucked. it needed to reload every 2 hits so I died right after that. its stupid that upgrading my weapon made it A LOT weaker.
also, like alot of people said, no save feature is BS. -especially in a game like that. i didnt want to satrt all over again so i prolly will never play this game again
overall: i played 15 minutes and it was really cool. then some stupid shit happened, i died, and im not playing again cuz of no save
