It's a nice mix between WfC and FoC. The limit of 15 waves is disappointing but, the game has a lot more variety than FoC. For those who don't know, all the maps have all the doors open from the start seeing as with the new unlock system there isn't isn't any need for weapon and item dispensers. In fact, the only thing money goes towards is defences. The mode features challenges e.g. Defeat 75 soldiers with the Path Blaster and every time you complete challenges (even story mode based ones) you get a box of varying grades, bronze, iron, silver, gold and prime the better the box the better the rewards. Items you get range from weapons to weapon upgrades plus T.E.C.H, Hacks and characters. Hacks are great as they give greater XP and the wonderful thing about the new unlock system is that once you complete a challenge you can complete them again, unlocking new boxes which gives you more copies of great items such as 6x XP, a healing drone or even the ball that creates a black hole which encourages you to be awesome. In the Escalation menu (rather than in game like WfC) you can select from a huge range of characters and the great thing about this is that you aren't forced to be someone you dislike simply because someone got to him first. You select a primary weapon you've unlocked, a heavy, an ability 3 T.E.C.Hs and 1 Hack. I believe T.E.C.H is limited to one round whereas Hacks last the match. Multiplayer abilities make a return with faves like Shockwave (renamed to Thunder Wave) and even Hover Slam. The great thing is you can give them to anyone. Yes, you can make Warpath or even Grimlock Cloak. Seriously! Something I'm liking about the 15 wave limit is how I can quickly make a new player and experiment. Difficulty is what you make of it as Hacks can make thing challenging and increase the duration of a match plus, some stages are harder than others. One criticism I have is that Edge of Reality didn't take into account that maps like Broken Hope were designed for a game that had control scheme and so without double jump, navigating the old maps can be tricky. Any questions?
