Quick summary: A nifty small game worth a few dollars and a few hours. Never have I yelled "Don't tase me bro" with such sincerity and volume. As of 12/1/2014 what you pay is what you get, no microtransactions or DLC.
No proper tutorial to point out the games features. Especially the UI.For example: Health is of course located at the top along with a "shield" however health is segmented, and as you take damage your health regens only a segment. In order to fully regen your health you need to either sprint to the health station or purchase an upgrade at the store via the somewhat hidden upgrade tab. I found the upgrade tab after maybe 3 failed games.
Levels are rather ho-hum. Little bits of moving machinery here or there to give some 'life" but theres no awe. Which helps in a a way, no real distractions while fighting. Levels feel legit like factories/storage units in which there would be plenty of robots. However they feel like legit factories and storage units, rather dull but serviceable.
Currently there are 8 enemy types each having their own range of somewhat charming taunts,Of which only one you will learn fear from. The taser-bot. You will feel the dread of Sarah Connor meeting the terminator in the 2nd movie as you are approached by its blue tinted fury. As far as the rest of the cast goes, they lack any real intimidation or "character". Which yea I get "robots, what character?" but it does leave ya wanting when games like Leaft 4 Dead and all of its Boomers, spitters, Tanks and whatnot exist.
You can have a total of 3 weapons by the end of a "Rush", your side arm, your main, and an "alternative weapon". Weapons feel about as good as they can when shooting against wire and metal, though a rather lacking selection of guns may put you off. 3 upgradeable weapons (standard shotgun, rifle, and sniper-esqu rifle) and 1 upgradeable side arm are what you choose between entering a match. As you play each match you accumulate points to spend at the shop which allows you purchase a standard/all around upgraded version of the starting selectable weapons (main), two preference weapons (alt), and two "experimental weapons" (alt). The experimental weapons provide a sort of "reward play" as they become accessable after so many rounds of accumulated points, you may destroy hordes of robots with dangerous lobs of lightning or incinerate them with essentially a laser cannon.
Your 4 upgradeable weapons are manageable in the combat profile screen, there you can view and customize your weapons and character though only somewhat. Armor is purely for looks, mix and match as you unlock, some weapons have alternative firing modes however scopes give "recoil reduction bonuses" which should be a pure cosmetic choice not a somewhat forceful upgrade. Aside from firing modes, the upgrade paths of weapons are linear. Your character also has a skill tree, after obtaining the trainee perks your able to choose 3 of 6 (plus 1 required) perks from each branch of Assault, Ranger and Support. While respec-ing is easy enough, its a shame they don't let you have multiple pre-sets of perks. The perks in question generally give damage or accuracy buffs or give a grenade or ammo clip ever 2 minutes. Nothing too amazing but the choices are decent choices as opposed to a blantantly better perk to choose from that its been paired with.
Picked up while it was 25% off looking for a cozy little FPS to play. The game needed some option tweeking before I could find a comfortable spot. Despite all the wish fors and occasional bugs, its a neat little time sink. Definately needs a shooting range mode or something to let players get somewhat comfy with weapons and settings.
