Heres a short demo of a "grabbing" technique I did in events. By pressing Q on your keyboard, you do a cool little animation and SE but if you're within range of enemies you'll pull them to you and they'll fight you. You can position yourself differently to pull a different number of enemies. If you stand inbetween the 2 soldiers in the demo and press Q, you'll fight Soldier*2, but if you stand out of range of one or the other you'll fight Soldier*1. This system can be expanded indefinitely, such as grabbing 4 or 6 soldiers, or even 12 (if your battle system allows that many enemies).
I know there are only 2 enemies so far, but I'm going to add a lot more tomorrow, just didnt have time today. Plus they'll walk around and disappear when they die (small changes). I haven't posted the tutorial yet because I want to tidy up the comments on the event first.

Demo.

Enjoy it....even though its short.
