Hey thanks for the feedback! Yeah for the level you're equipped with only a chest mounted gun, in game reasoning being that you're a rookie and they didn't want to spend more than necessary for a test mission. I figured that it was "alright" since in games like armored core, unless you manage your ammo and/or equip a melee, you're boned if you're out of ammo. I did want to add a melee but ran out of time.
Thanks for the solution to the resolution thing! Like I said, I'm not too familiar with configuring UE4 to be played in different resolutions and aspect ratios >_>
