Really enjoying the update! Regarding the grenades: personally, I think the issue with other grenade types is the low capacity and how it's launched. Unlike missiles that are fast moving and have larger capacity, grenades need to be double tapped, can't toggle off the lock once pressed, and require extra effort in leading the shots, and they seem to do roughly the same damage as missiles, whereas both missiles so far can be spammed in quick succession, are fast and travel straight. So I always opt for missiles as they are easier to approach. I hope the grenades can be looked into eventually if they are not the focus right now. Another potential cause is that most buildings can be bypassed easily with your primary weapon so it's easy to open a way for direct missile volleys. Tougher or even specialized structures (like panic walls in Brigador) that make easy missile/gun hits a challenge can incentivize use of grenades, just a thought.
Thank you for playing again!
I'll see if I can have maybe a setting to change how the grenades function, like having it so you can hold the key down and then once you release it'll automatically launch. I admit they're not really the focus right now, but they could definitely use some further emphasis in the gameplay. The idea of having special structures to destroy is an interesting one, thanks for suggestion.
