Decide what you need to shoot
The simplest way to conserve ammo in DERELIKT is to check which rounds you actually have and spend them where they help you move forward. Before firing, look at whether the threat blocks the route you need. If you have a clear way through, you may be able to keep those rounds for the next room.
Check your ammo before switching weapons
A rifle in your inventory does little for you if you are carrying ammo for another gun. In one early preview, the player expected to have assault rifle ammo and found they were out. Later, they switched back to the pistol to save their heavier weapons for another encounter.
Use that player experience as a decision rule. Check your compatible ammo before relying on a weapon, then choose based on your stock and the encounter ahead. A lower-pressure stretch may be a good time to use the gun you can afford to feed.
Weigh the value of a Satchel Charge
A Satchel Charge can deal with a hostile creature or a security drone. It can also blast through certain damaged doors and other weakened obstacles. Before throwing one into a fight, consider whether you passed a barrier where that same charge might open a useful route.
The official DERELIKT exploration announcements describe returning to previous areas with new equipment. Some of those detours can lead to a stash of ammo or medical supplies. Remember where a weakened door was so you can decide whether to return when you have the right tool.
FAQ
Should I always use the pistol to save rifle ammo?
Check what you have on hand. The preview player saved heavier weapons by switching to the pistol, but your best choice depends on the rounds you can spare and the threat ahead.
Can a Satchel Charge help me find more ammo?
It can open some damaged barriers. A detour may lead to a supply stash, although the contents vary by location.
How can I avoid getting caught with an empty rifle?
Check how much compatible ammo you have before committing to a fight. Keep another weapon available if your preferred one is running low.
