Since I started playing 5K, everyday I run though either wave survival or raid on axiom outpost. Both game modes are really fun I and enjoy challenging myself. During these runs I have found a few issues with the NPC's. The raid game mode often has issues with spawn points or pathing. I have a route I run and without firing my weapon, I can avoid 90% of the guards. The spawn locations are good, attempting to block your path from files building, to the large water tower, then to the storage building, and the giant facility.
NPC's get caught on the stairs of the water tower and the grass below.
Going to the storage building to capture it NPC's get caught on the under landing of the building next to the storage facility (easy for grenades).
In the giant facility, going to the objective, there's a glass wall and a door that leads from the courtyard to the objective room, loads of NPC's funnel there and get caught on each other.
Turning off the electric fence, there's large containers which block NPC's and there's a door that leads to another room and it is a large bottleneck for NPC's.
As soon as you're at the radio tower, its a free run back to the truck. NPC's that spawn at the truck or at the water tower roam away from the truck, allowing me to run around the giant facility and back to the truck, or you can just shoot them all before running.
Overall I love this game, its gunplay and the small details put into the firearms. This is a small gripe I have and would love to see this reworked.
