It's tricky to unpack what's going on exactly without having hands on the demo but I think the energy weapon is using new clips for "ammo" (a battery from your previous post) rather than drawing on suit power isn't it?
The shield definitely is using suit power (which is less than 100% on both players) but it does look to me like the shield is the only draw when firing the weapon ... maybe someone analysed it more carefully than me though.
(No idea where the jetpack energy is coming from, even though there does seem to be a sound coinciding with the jump. Could be a coincidental sound, could be don't know where the jet is drawing power from. Again tricky to unpack. This demo raises more questions than answers!!! hehe)
It is a bit tricky to unpack everything, so I went back and watched the playthrough (again) in slow motion - sound off, there was no need for creepy 25-50% speed commentary. Bearing in mind the previous Dev post about the Odyssey Hud, it's possible to understand some of what is going on:
1. The Combat suit can carry 5 med kits vs the Maverick suit which can only carry 3
2. There are 5 icons on the Suit Power bar (Yellow bar on the lower left Hud). These icons light up when power is being drained for different actions - from right to left:
- 02 Icon: Life support, possibly default, it is lit up most of the time. It is not lit up when Circe is inside the building.
- Shield: This lights up occassionally and appears to coincide with the fire fights and shield regen (6:00 - 6:40)
- Tools/Utilities: this lit up when the Ark Cutter was used (3:55), and the Energy Link has the same symbol on it. There was also a massive power draw when the EL was used to overload the Door/Airlock (4:20)
- Weird 'Arrow': This kind of looks like a jumping icon? Maybe the jetsuit jump assist? - this never lit up.
- Temperature Guage?: Well that's kind of what it looked like to me - this never lit up.
- EDIT: the last Icon (Temp Guage) does not appear in the screenshots shown in the Odyssey Hud Breakdown from December, so that's a new addition since then.
They definitely had some difficulty with the mission (ie it wasn't a single play through). There were times when Nestors shield was completely gone, but then it was full in the next cut scene. Also, it looks like Circe repowered his suit inside the building during one of the takes - his suit power jumps from 52% to 100% after the cutting/overload scenes - but then is back down to 38% during the runaway scene.
