I have concerns that might be addressed later but for know just the good I found in the walkthrough trailer.
And in about 9 hours from now we'll have more information.
Shooting the create for loot
In the beginning you shoot a hanging create for loot; awesome!
The Yelling Enemy NPC
At the beginning of the control point the NPC was yelling some nonsense; love it. Good to see NPCs being apart of the world. In TD1 they always seemed to me to be disconnected from the world; like they'll placed their but not living in it.
The heavy elite armour destruction.
This is a big one for me because it looks like they can take multiple bullets; seems believable.
The weapon UI in the Inventory
This looks awesome. The damage drop off graph screams RPG and I love it. Please don't remove this graph.
The foam thrower enemy
Weird to me at first but looks like a new semi-believable way enemies can engage us in combat.
ISAC analyzing the world
Showing what's happened in the environment. High explosive fragmentation impact on the plan. More ISAC environmental descriptors would be kool.
The talents on the weapons
They look more creative that just a % increase to a stat. +10 points.
