Infinitly spawning enemies

[Zelex]

Infinitly spawning enemies spawning enemies get alittle overwhelming in solo, you run out of ammo really quick if you dont rush through and ammo drops are compleatly random instead of what you have. Multiple times both my guns have been empty and ive been surrounded by ammo drops that i couldnt use.and if you want to take your time enemies seem to stack up in other rooms or they spawn faster than you can kill them in parts. trying to take down three shockwave walkers with 2 drones sheilding them when your out of ammo is a challange. and its cause i got pinned down in a room till i ran out of ammo. I feel there should be a finite amount of enemies that can spawn before you move areas. but then again, maybe im just bad
