Despite the looks of a some HALO multiplayer (which I never played actually, only viewed), it plays nothing like it because of generous amounts of splash damage weapons and tools, and several other mechanics which would be game-breaking if it was not for the DOOM universe in the first place.
Basically a mix of Quake and Unreal, more modern, but definitely not too competitive. Maybe the should add a bit of dynamics other than this double jump, or replace it completely - it's too casual for really good and complex evasion mechanics, there's not much place to learn. Skin system as complex as never before but of course it has nothing to do with the gameplay, and I hope (probably in vain) Bethesda won't hop onto the skin trade bandwagon.
Obvious problems that I experience:
- a 3-meter melee attack, as if these guys have a yo-yo attached to their wrists;
- shotgun is too short-ranged and widespread, it encourages people go nose-to-nose (or rather nose-to-ear);
- and still at this distance and speed hitting with these weapons is like trying to swat a fly out of air - considering latency issues, which otherwise not too bad;
- all the action combined from my favourite AOE tactics (plasma ball + vamp grenade) make the enemy completely dissolve into the special effects and hit markers, too difficult to see at all;
- stupid "electro-gun", which is so raw, I can't really define the importance of it - sure you can hit for 60 full-charged in the first hit, but by the time you switch to your next gun you are pretty much mincemeat;
- well, being demo and all, only two maps, two modes, one demon, handful of weapons and a level cap of 15, I expect this to be fun game later on.
Ah, you can even sucker-punch an enemy revenant if you are so good at this. Totally worth it.
