Fantastic down time game. It's immersive, responsive, and very addicting. Mostly though, it shows massive potential. A few friendly recommendations: - QRA engagements. It would be very handy to see exactly what stage of interception (ident, show of presence, show of force etc) the sorties were undertaking. That way I can make sure the sorties are doing exactly as commanded. - Redeploying assets ahead of starting the game. For example, tankers are all concentrated onto one airfield; which means if I am to have true dexterity in my decisions I have to send a load of tankers across the country at the beginning of every game. Other than that, this is clearly a very well thought out passion project, with a diamond solid foundation. It just needs a bit of love and guidance for user friendliness. I look forward to future updates
Air Defender is to an ATC sim like Tower3D!, what MS Combat Flight Sim is to MS Flight Sim. Basically you are a military radar operator / air operations coordinator during the last days of the cold war. You're looking at a composite radar screen of the British Isles and the nearby European mainland, trying to determine if the contacts are incoming enemy aircraft trying to harm the nation. It is more of a simulation than you might expect - there's not much hand holding, and things mostly happen in real time. The actual display is a 2D composite radar display - think a lot of green to replicate a CRT - simulation with quite clunky controls that are no doubt reminiscent of the real thing So you'll see the map with a ton of tracks - mostly civilian - and start working through categorising them as "assumed friendly" for most civilian traffic, through "unknown" and "suspected hostile". To get confirmation of hostility, you may launch interceptors to ID the aircraft, if necessary warn it to leave UK airspace, and escalate all the way up to engaging the enemy if they don't respond, or show hostile intent. The enemy will sometimes be obvious - approach from the North Atlantic without the correct squawk or any kind of flight planned route. Other times they'll spoof the system and try to infiltrate UK airspace by looking like a legit civilian operator. So this will require the player to investigate tracks and look for irregularities but I will say at this stage the irregularities are seemingly quite obvious to spot once you're looking at a track. This is complicated more by the sheer volume of tracks to look at rather than analysing the data itself. In addition to initiating and managing fighter intercepts, there's mid air refuelling of those interceptors to consider, movement of supplies and aircraft around the UK to place them for best effect, AWACS aircraft and a few other management features. Also to investigate an aircraft, there is a rudimentary way of contacting civvie ATC units to enquire about tracks that are suspicious. While doing this, there is a limited but very effective amount of voice acting already that nicely fills in the imagination gap about what is going on out beyond your radar display. You'll here interceptors launch and then progress their intercept procedures and a few other radio calls. But - its EA. So there are bugs and inconsistencies - it's playable but some of these bugs in the UI do get frustrating. There's also a distinct lack of QOL features - as I emntiuoed the civilian ATC interface is just a basic set of commands to type in to a text box and that process gets old quickly. The voice acting I mentioned is very limited too - I really wish there was more of this because it adds so much to the atmosphere. It's also more of a sim - not a game. For me that's awesome, there are plenty of games about apocalyptic outcomes, I like the focus on a single aspect here. But if you're wanting more of an RTS game or a dry logistic strategy this isn't it. What I'd like to see developed? At the moment it seems to be very cold war focused. I'm sure a lot of the day of a cold war radar operator was indeed spent looking for Ivan's Bombers. But I'd like to see some more general stuff going on like civilian emergencies, maybe even a hijack, some civilian SAR coordination, and that kind of thing. The engagements at the moment are quite dry - do the intercept and get a basic ID. This is quite limited at the moment - I'd like to see and hear more from the pilots about the contact they're intercepting. And if it gets all the way to engaging in combat, how about some CSAR to pick up survivors? And while we're at it, focus on the Sim aspects in terms of the radar and display functions. Are there some failures that can be modelled? Jamming? Stealth aircraft? Things that may require the player to delve into the technicalities. Anyway, If what I've described sounds interesting take a look. I think it could be a really great addition to the sim scene and something which is unique for what it simulates.
