Poly Station 5 was ment to be a play on Playstation 5 which during it's release made stores extremely crowded and even ended up with some tuggigng and even fights over the console. The "shield" is acually just a simple stun that stops attacks if an enemy is hit. Weapons have some mild chnages some are better in one statistic and worse in others but they are all a simmular enough to be vaiable weapon in all situations
