Using a second power on an enemy currently affected by a previous ability will cause an explosion that deals quite a bit of extra damage - as well as area of effect too, I believe.For example, using warp on an enemy right as he's being lifted/pulled, etc.
Like I said, Ive been pulling thr AK 5C.Not exactly a pro player but the drawbacks to muzzle attachments seem to outweigh the benefits (accuracy, bullet drop, etc. compared to stability or invisibility on the radar).I was debating playing with the suppressor. I use the muzzle brake now, but I'm conflicted. Sometimes play with no muzzle attachment at all.
Muramasa: Demon Blade. It's a beautiful side-scrolling beat-em-up. Subjectively not kid friendly though, you may want to look into it (rated Teen).
Okami is also very unique, but again not really geared towards kids. If you want to just enjoy it yourself though it's highly praised.
