I can give you some simple ones that you'll probably learn early on. Caution is your friend. Wading into enemies won't end well. Watch and learn who and what each one is, and pick your targets by severity of threat and who's closest. Parrying is good for human enemies, and is a handy thing to know, if you can pull it off. But the risk that comes with it is high if you fail. If you've ever played any lost planet well, then no doubt, your best, and let me say it again, BEST tool given to you is rolling. But even that takes some time to learn.
