Abandoned Lab

Overview

 * There are time limits before waves 3, 6 & 9 - 1:30 min. each, and in these waves enemies appear only from upper spawn point(s), like in the first 2 waves
 * The game starts with 400 resources & 10 bases and the reward after each wave is 300 Resources & 8 bases
 * It is one of the four maps in the game, that have two cores to defend, the other ones being Cliff lodge, The labyrinth & Power relay
 * There are 6 orange mines in the map (links in Youtube & Steam - [1 ], [2 ]). They are technically level 2 AR mines (9500 damage per mine)

Notes & tactics

 * This is one of the toughest maps among the base game's ones (if not the toughest among them), so it is wise to be careful with the dificulty setting
 * Skye and Sweet are good choices for this map. Skye can stack damage bonus with the Drone Launcher and Sweet is good vs crowds and Soakers
 * The Drone Launcher as an auto target-seeking, which seems useful for a large map like this, but it shines mainly vs the heaviest enemies
 * The Voltaic Hand Cannon is good for enemy-seeking across a large distance, and in case enemies get close to you, they can be lined up along the ramps to penetrate all of them at once. However, it has some minor drawbacks - if the Impeccable accuracy feat is enabled, the secondary fire might not be able to outrun a runner for a very long distance, allowing it to even reach and hit the core
 * If you stand on the catwalk right above the Northeast Spawn, you have a long straight line-of-sight to the South and to the East, in addition to having close access to the lower-level. You can use Drone Launcher to shoot downward toward the lower-level, while using Voltaic Hand Cannon 's primary fire to attack upper-level enemies in a straight path.
 * If doing the map with 5 or even with just 3-4 feats of strength, it is recommended to be at least level 40, due to the high difficulty of the map and the capability of changing the main weapon after lvl 40 on
 * The Focus is a good choice, although effective mainly vs the enemies from the lower spawn point. The lower level with the area, closest possible to the lower spawn point is susceptible to Focus, since there it can find full utility of its range
 * Violators have good range and can cover both upper and lower sides
 * Lightnings can be put in U-shape/X-parts parts of the maze, so that there is more chance to damage enemies 2 or more times by it
 * While the Anti-Air can help a bit in wave 6, it is mainly for coop games without the Hardcore feat and for Survival mode, since here are just a few Spitflies
 * Weapon perks can help greatly, e.g. Tactical Juxtaposition can make Drone Launcher and many other weapons more effective.
 * Reinforcements and Slowing Rounds can help to distract and delay the enemies.
 * Unstable Core can help a bit vs escaping enemies, although it is effective mainly vs the small Runners and Walker Pups
 * Upper Class can be good if standing on the highest point of the map (e.g. via Skye's double-jump to get up on the pipe), where is a good view of everything.
 * A wise strategy is to let towers to cover the lower-level (Northeast Spawn), while you take care of the upper level.
