About Lambda Wars with 14 comments by Sander on Aug 20th, 2015

Last Wednesday we released our biggest update yet! This update includes three new units and two new buildings, many balance changes and improvements.

First off we replaced the Rebel Partisan with an updated version. This unit has two main attacks between which you can switch: throwing molotovs or stinkbombs. Molotovs do light damage at units around the target area, while stinkbombs slow units down. Second we got the new Riot Metro Police, equipped with a shield and stunstick. In offensive mode, this is a fast moving melee unit. Using the station ability you can deploy the unit, generating a cover spot for units behind the metro police.

Furthermore we added the Rollermine to the Combine, which you can produce at the also new Mechanical Factory building. The Rebels got a new Offensive building, the Teleporter. Using this building you can teleport units to anywhere on the map, as long as you have vision. A teleportation takes 40 seconds to complete. During this time the units being teleported are unusable and rift is created at the target location, visible to enemies.

hmm.. if this is to be compared to UDK, then you would have to be able to make any kinds of games with the Alien Swarm SDK and not just mods for it.

so is this possible?

This game is soo fun. With the console commands i figured out from a steam news update, its even better. L4D-esque horde spawns add a little spice, especially when tweaked a little to specifications. It made soloing Landing bay on easy, well, not so easy :P but i actually made it through one >.^

for a free game, this is one incredibly fun sci-fi creation, building on steam's co-op capabilities, which gives it immersive replay value, making it an awesome return-back platform for general cooperative-skills practice with new gamers and relaxing eye-hand coordination training gamers usually seek. given its free access to the game's sdk, enriches the experience even further, adding various creative production of new game content based on valve's source engine. what would u need more from a top-down…
