make it so the ai actually can clime over the sand bags.. make it realistic. Also Make Ai spawn far away give human players atleast 20-30 seconds to spawn and you know prepare for the attack.
Blucher for the love of god learn to use Capital letters
and how do you suggest making the AI able to climb over sandbags without making the ground high or the sandbags tilted.
And the only effective way of slowing down spawn,I'm pretty sure is just giving them a long way to come or something similiar.
Oh and it's good,I'm glad it's been made at a good size for gameplay rather than the actual historical size.
