Two of the Five Parsecs titles so far (Bug Hunt and Salvage Crew) involve finding stuff on the battle field.
In Bug Hunt you have Tactical Locations.
These are sort of a short-hand for all manner of things that can work to your squads advantage: Alarm or defense systems, bulkheads that can be closed down etc.
Investigating a location allows a roll to determine its feature: Distract aliens and prevent them from moving for a bit, block access to the area, remove alien contact markers from the table or delay the arrival of more alien contacts for a while.
This does require a die roll, so make sure to bring someone with a good Tech skill.
If you like the "fortify" scenes from Aliens, that's essentially what is being represented here.
Salvage Crews instead have to deal with Points of Interest.
These can represent any manner of stuff you can come across in the battle area.
Toxic waste pools, computer consoles that open up a stash or more bad guys, you won't know what you find here.
In both cases, interacting with the objects is optional.
Bug Hunters will typically want to do so, since the worse case scenario is that you don't get anything out of it but if you're lucky, it could give you an edge against the alien hordes.
Salvagers have a bit more of a decision to make as a PoI can prove dangerous (or even result in running into monsters) but could also furnish you with more loot.
Future Five Parsecs releases will of course feature similar mechanics too, when appropriate.
The upcoming black powder rules will feature a pretty good range of possible encounters to have in the middle of a spirited skirmish with the enemy.
