Review of Undertow bot play:16 player online, two modes -- Team Deathmatch and Conquest (capturing spawn points). There is no free-for-all. The game always requires an even number of people for teams. You can play any combination of bots and people, but each team must have even numbers. For example, 3 people vs. 3 bots, or 5 people/3 bots vs. 2 people/6 bots, etc. The bots have four difficulty levels. This allows for a small group of people to team up against the computer, which is great fun. Matches can be tense and unpredicatable.
