Lambda Wars Update 26 June 2017 (3.07a)
Game modes:

  • Work-in-Progress game mode "Squad Wars". This game mode is far from done, so don't expect it to be exceptionally finished, playable and balanced. Also, IT DOES NOT SUPPORT CPU!!!



Character Units:
  • "Chars" - units specifically for "Squad Wars" game mode. They have unique abilities, attributes and stats.

Balance:
  • Explosive bolt now requires a munition depot.
  • "Fire" attribute now deals more damage against "creature" attribute (all non-human units, except synths and mechanical units).
  • Floor Turrets no longer require population. Previously they required 2 population.
  • Floor turret damage increased from 6 to 8.
  • Combine Elites now require both AR2 and Shotgun to be used.
  • Damage taken by units inside bunker was reduced even more now.

Maps:
  • hlw_outland and hlw_waste - added manned turrets and floor turrets as early defenses. They become owned by the player that captures the closest control point.
  • sw_woodland, map hlw_woodland, but made for Squad Wars.

Improvements:
  • Improved veteran steady positioning.
  • Shield Generator can now be destroyed if it's unpowered.
  • Annihilation: No longer require useless structures like billets and energy cells to be destroyed. Only buildings that can produce units are required to be destroyed. The rest can be ignored.

Chars (Squad Wars):
  • Commando - Can shoot while running and tosses grenades. Can switch between a shotgun or an AR2. Very slightly reduced movement speed. 1000 HP. ASSAULT unit.
  • Elite - Equipped with an AR2. Can shoot energy balls that may harm his team. Deals increased damage. Slightly reduced movement speed. 800 HP. DPS unit.
  • Mechanic - Equipped with a pistol. Can produce manhacks, place floor turrets, set mines and place automatically constructed aid stations. 900 HP. SUPPORT unit.
  • Riot Tank (WIP) - Equipped with a stunstick. Can switch to SMG1. Can make cover spot for his allies to use. Is fast with his stunstick out and slow and more vulnerable with SMG1. TANK unit.
  • Scanner - Equipped with an SMG. Has abilities to deploy scanners and scan an area in the map for 15 seconds, as well as reveal invisible units. SCOUT unit.
  • Scout (WIP) - Equipped with an SMG. Can go invisible and stab enemies (doesn't work yet). Large view distance. Fast speed. 900 HP. SCOUT unit.
  • Flamer - Equipped with a flamethrower. Can toss smoke grenades. Slow speed. Short view distance. 1200 HP. TANK unit.
  • Veteran - Equipped with a crossbow. Can shoot explosive bolts. Has 800 HP. DPS unit.

Status Update 15 - We're back baby!

Hey Commander!

A LOT has happened in the past few weeks. For example, Mr. Darkness has been to White Nights Business Conference for Game Development, which has been a positive experience for him, and will be in time for us too. I have concentrated on staying in the background and working on some other, exciting things that will help Vortal Storm reach a new level. More on that in a bit, though, let's start with what we always do..!

Community Update

Unfortunately, due to the absence of a lot of VS Staff Members, the community took a bit of a dive again. I hope that this picks up sometime soon, I will be speaking to several other folks on hosting some games and streaming them, but I cannot promise anything right now.

Development Update

As we have surpassed the half-year mark of 2017 already, we have set to thinking after White Nights. Lambda Wars is great, as we all realise, and will never be put under payment (as some people feared). It will remain a free mod from now until the end of times.

However, the future of Lambda Wars is discussed in the next segment.

So what hell is goin' on 'ere?!?!

Allow me to start at the beginning. Darkness did his part for Vortal Storm by attending a business convention in Russia which has shown to be very serious in its development. Giving both Darkness, and myself in turn some food for thought, we have come to a few conclusions.

Lambda Wars, while great, will not be Vortal Storm's one-stop-shopper. As we realised, it is only the beginning. Darkness and I speak of our next project a lot, which will feature Unreal- or Unity Engine. However, exactly what it will be is unknown as of yet.

We have, in collaboration with the above, decided to step up the serious vibe to the upstart that is Vortal Storm. Rather than just a bunch of collectives to one goal, we will now be attempting to grow, and hopefully - one day - establish ourselves as a company, and even have an office somewhere. (One can dream, right?)

And continuing on the 'serious vibe', there have been changes in staffing as well. As you may have noticed, some of the developers have been removed off their rank in order to restructure some.


And... As it stands, I will take official distance from my previous task as Community Manager. I will make way for Cupid, who will fill my shoes as Community Manager, and I will continue within Vortal Storm as its Chief Administrative Officer, running Vortal Storm together with Mr. Darkness.

So, it's not really goodbye if I'm not leaving, but I will take a lot more distance from the official community tasks.

I want to thank all of you for the wonderful 7 months of work I've been allowed to do within this community as its manager, but it's time to look ahead, and take on new challenges.

The Future of Vortal Storm:

The future of Vortal Storm is not etched in stone right now, but our next focus is to assemble two teams of developers. One small team to stay working on, and bugfixing, Lambda Wars.

The other, larger team will work on a new game with us, that will be applied within Steam again at a price, which is our next step forward.

We hope to see you sometime!

Husky & Darkness.
