Hello Zoberk,
glad you like how the toolkit looks. I’ll try to answer your questions to the best of my ability. XCOM was one of my main inspirations for the toolkit, and is a kind of TBS game the toolkit is especially well suited for. I am working on a cover system at the moment, and I can share my solution with you if you’re intested. It will be in the next update. Abilities with cooldowns is certainly possible to add. I’m working on an ability system as well at the moment.
You will need to be quite comfortable with both Unreal Engine and my toolkit befor you begin to make major modifications, however, so it is good that you are not in a rush. All of what you are describing is certainly doable, but will take work. I’ll be happy to assist you along the way through this support thread.
