The spawn mechanics are so fucking bad. Really bad. Pop up in your face bad. It just wipes out any tactical level of play. Enemies seem to spawn in at both intervals and triggers, and within a certain radius of your mechs. It can lead to situations of mechs and vehicles attacking from a place you passed through 20 seconds ago.
AI in the game is poor, and it feels like most of the bad spawn mechanics are there just to hide this. Target fixation and bad pathing are really noticeable.
Mech piloting is okay. I've played MW mainly on a m&kb throughout the years, and there probably isn't any better way of doing it than the way MW games have been doing it over the last few games. MW5 pretty much keeps to that standard.
Equipping mechs feels a bit restricted, but loadout rules have changed many times since the birth of Battledroids. (This may be the norm in current TT rules, I've been away for a bit).
As others have said, graphics are... fuzzy? Blurred? It feels more like bad communication between the engine and the assets rather than a fault with either. When it first loaded in I thought it was set at 720p. I imagine some tweaks and shaders will surface soon.
The story is pulp revenge tale, and I'm okay with that; I wasn't heading in to this game for a page turner. Voice acting is okay, and that guy who did Adam Jensen in the new Deus Ex games has a character. In-mission soundbites are nothing special, and lance mate call-outs are distinct enough to give information about what's happening on the field.
Overall, this is a mech arcade game rather than a mech sim. The spawning is so bad though... Really bad.
