Great old arcade game I never knew about. Maybe its a sequel or the original version of Battle City for the NES. Very similiar to that game but with alot more going on. Might try a co-op playthrough when I KILL it off for arcade on MAME. This is the Switch version. Doing this version solo. Might put up a tutorial as well.
The goal is to clear each stage, you have 3 lives and unlimited continues to beat a stage. Some stages have bosses too. Main goal is to clear out all the enemies, including bosses and protect your base, which can be destroyed by the enemies. Once the enemies break the border around your base they can destroy it in a single hit it seems like. So you have to guard that as well. Great combination of slower but twitchy, precise aiming and movement along with strategy to set enemies up a certain way, find the optimal positions, etc. Very good.
