Either I am blind or there are no objects other then sparrows that can be shot and blown up. Now I know this is a cliche now days but it feels like its missing! Have you been sniping and wished there was a barrel, power core, unstable plant or something you can look for to change things up a bit. Without these elements the game feels so scaled back or bland. I mean theres a strategic side as well as visual or atmospheric side to explosive objects. These places arnt going to be so clean or not have such things.
Nexus strike has those yellow boxes that blow up (I asked what happens if I punch this and found out the funny way) also on mars there are small power cores that go boom with a couple shots
You can line up cursed thralls and then shoot one and they all explode in order. It's amazing. You can also use cursed thralls to damage other enemies. Have fun!
There are tons of things that can be blown up. Next time you are playing look for anything that has a pulsing orange light. The round containers on Venus are just one of the things you can make explode.
