Alien Covenant; WTF Human Tech compared to prometheus

The human tech in alien covenant was so primitive, the ships, the medic center, even the weapon is a joke..., the suits? camp suits?

The action detail is also too shallow compared with the prometheus

The weapon is a joke so the human may in the damsel in distress position? thats just too lazy.. make a great weapon with more number of alien as it should cause they breed easily!
