I need more guns for Deep Cave 15 enemies, but there's not enough room to add more guns because passages are too small & weapons block each others' shots. It's pretty frustrating.

1. You need weapons to kill enemies.
2. You can't armor weapons.
3. Weapons can't shoot past your own machine's blocks/armor.
4. There's no way to protect your weapons, they have to be exposed.
5. Enemies immediately break them, rendering your machine unable to kill them.
6. It becomes almost impossible to progress.
