A more combat-oriented stealth strategy game with cover, freely deployed traps, and chances-to-hit based on each character's level of mastery of certain firearms. If setting up ambushes is not your thing, the game can be played slowly and more-or-less stealthily, attracting enemies one by one with lures and whistling to knife them - and this seems necessary for some achievements - but it is more frustrating that way, in part due to bugs and controls. I experienced quite a few issues with traversal, picking items off the ground, items vanishing from inventory if sorting too quickly, several crashes, and general lack of responsiveness when controlling characters, which hinders swift playing. Literally every action is performed with a simple left click, which becomes problematic when there are multiple interactive objects too close together.

Remember to always perform melee attacks on enemies from behind or from the sides, as they waste almost no time going into "red" alerted state when confronted up close, thus probably ruining the achievement run even if neutralised shortly afterwards. At a distance on Normal difficulty setting, enemies' detection times are pretty forgiving, though. However, some enemies turn their heads, and officers have a much wider field of view. Annoyingly, windows are treated as perfectly transparent openings at "ground level" and do not hinder enemy vision at all - bodies and characters in a room will get spotted by enemies patrolling outside through a window! The only way to hide a character by the window reliably is to click to take cover by the window sill. In addition, accidents will always attract nearby and sometimes even pretty remotely positioned enemies, and cause them to go into "yellow" search mode.

Each operative gains experience to level up and improve abilities. The descriptions on some of them could be a better, and there does not seem to be a way to reset allocated skill points. Some abilities seem more useful than others, so save in advance to experiment freely.

There is loot to be found in the levels and stashed in the operatives' inventories, even if said loot is pretty scarce in the name of balance. Some of it has to be taken back to base where it gets converted into food and "supplies", while some of it can be used in combat - stuff like weapons, ammunition, mines, grenades, lures, and healing items. There are no silenced weapons, but gun shots have limited noise range. There also don't seem to be any heavy weapons. Keep in mind, that loot cannot be placed on the ground or in containers for sorting purposes, only discarded.

Managing the base of operations is a cool concept, but it feels somewhat undercooked. It may eventually start feeling a little tedious having to assign tasks to each squad mate - things like procuring food or supplies, and performing passive "missions" with a chance-to-resolve. On the other hand, if you end up feeling some emotional attachment towards the characters, even such basic management along with equipment sorting can add to immersion. Problem is, the characters get very limited exposure because there isn't really any dramatic story here - the campaign feels more like a pack of independent missions and ends pretty abruptly.

The game features an entirely optional Hard mode which disables manual saving, and Missions mode which allows for replaying five levels with modifiers enabled to increase difficulty (only the latter mode has achievements for playing it). Get comfortable with level layouts and game mechanics first because the reinforcements modifier seems pretty savage - it spawns squads of enemies after certain time intervals, and they just bee-line to engage player characters. Still, it can be fun to run away from them through pre-mined narrow passages.

All in all, it is good when it works, but it really needed more time in development - if for nothing else than to work a bit more consistently.
