Very happy to say that I've finally earned my Proximity Mines that come along with Level 53. It's one of the reasons I've bought/played the game, as it was a favorite on the N64 as well.
Having never hacked my game/console, it's great to have this in my loadouts, besides enjoying it in Heroes. I've played about 15 games now with them and already caught myself smirking when someone runs into one or knowing one saved my life.
I hoped there would be 3 proxies like with MI6 Heroes - but only two. I've already been killed while staring at a busy intersection thinking the best place to plant one, and my average game score has gone down while I'm changing the way I play the game a bit, but damn am I glad I've stuck with the game - anyone losing steam keep with it!
