It’s all pretty standard stuff, but there’s more to these tools than just navigation. It isn’t all about thinking your way through. Sometimes, you need to crack some skulls with a giant wrench. Combat isn’t the main focus here, as most enemies and boss fights are treated as a problem to solve rather than a head-to-smash. Most enemies can be defeated by just spamming attacks and the occasional dodge roll, but it works for the type of game this is. I would like a lock-on, but it works for what it is. You can also use the various tools you craft throughout the game to help make dealing with enemies easier. Arcade Archives CONTRA Switch NSP
